Thanks guy. My goal was to make it as powerful as possible, while still operating on 93 octane pump gas alone, remaining naturally aspirated, (no power adders nor forced induction) & keeping the factory stock body & the stock hood since I never liked those big ugly boxy looking 4" & 6" fiberglass cowl hoods. That's why I chose the huge engine. So that I can get lots of torque and power. By 3,000 RPM it already makes 715 ft/lbs of torque, & 775 ft/lbs at 4,000 RPM, along with 800 HP at 5,900 RPM
William Gruce dude your a good the car is flipping fabulous I wish I had the money for a hot rod I started a family young but my dream is to have a car like this
Wow, those are SERIOUS #'S, can the frame, etc. handle that and do you still use the 12 bolt ? Would that be a drop in for a 1st gen. Camaro? Some guy on here has a similar engine in a 72 El Camino and with 410 gears runs mid to high 10'sNice old Riviera in the background
looking at cars like this and hearing them is such a healing to the soul of an american,the wonderful heritage of our country at a strong point.....thank you for building and and keeping it going...........hats of to you bro!!!!
803 on pump gas is just plain awesome !! I envy you and this engine! (thumbs up). You need to run your car and see what she can do. My car hasnt been dyno tested but (last week) the car ran a best of 11.3 @ 124mph. The car won't hook for anything. Once I get this figured out, she'll run low 10s on pump gas. The turbo seems to help me keep up with the bigger engine drag only cars! ;) ;)
awesome sounding. headers really make the crackle even better. i have a 454 with a procharger. my way of getting more on pump gas.... wish i had it when i had my chevelle.
@captainghost82 Yeah, you go in stages with this hobby/sport. I started off taking my brand new 2003 Mercury Marauder to the dragstrip back in 2004 and I was running low 15's with it. ofcourse that wasn't enough, so I progressed through the 14's 13's and then finally into the low 12's once I installed one of those small under hood roots superchargers from Magnuson. I ran 12.007 seconds with 1.6 second 60' times on DOT radial tires with only pump gas in the tank. Now I'll be in the 9's w/this car
Hahaha...thanks. I'm glad you like it. This car has been undergoing some changes. It still pretty much looks the same, and with the same size engine too, but I pulled the engine out of the car to address an oil leak from the rear main seal, and it snow balled from there. I bought new Brodix Dragon Slayer 365cc cylinder heads for it, and a bigger/more aggressive solid roller camshaft that will result in a total lift at the valves of .817" . It's going out to the machine shop to have the decks of the block shaved down to yield a 12 to 1 static comp ratio too. The idle should be even nicer sounding when I get done, with about 50 or more extra horsepower still on 93 octane pump gas. However, I'm also in the middle of other upgrades such as suspension.
@mekall57 I'm glad to hear that you're a fellow enthusiast. It seems that a lot of people have forgotten what true American muscle and the great V8 engine growl is all about. There's just nothing like it.
Damn!! looks great! sounds even better. guy on HotRod in the good ol days had one he was building, i remember his arm fit in the exhaust... anyway, badass ride you got! cant wait to see more
I have a 350 small block bored 40 over, decked 25 thousandths, hypereutectic flat top pistons, a double roller timing chain, a Jegs 500/505 lift cam, ported & polished 1.94 camel hump iron heads, headman headers, a Bowtie Victor JR hi rise intake ,a 600 holley cfm carburetor! 3:73 posi rears and a turbo 400 transmission, it runs good for what it is, I've ran a 13:80 at 102 mph before but I would like to be in the 12's!
ok will do. BTW, I too have the 3.73:1 rear gear ratio, which I think is the best compromise for a street/strip car without having an overdrive trans. I too have a TH400, and with a transbrake and reverse shift pattern along with a ratchet shifter.
Cool, I was thinking about getting a set of 4:33's because I really don't drive the Chevelle to far from home when I take it out! I do love the feel of those low gears, I had the housing from my dad's GTO JUDGE under it back when I bought the car and they were 4:33's, I fell in love with those gears, they woke that Chevelle up in a big way!
5.7 litre chevys are great for cruisin. I have a 91 Silverado with a 350 and it has plenty of torque to get you moving. she'll smoke the factory tires from a standing start easily even tho it's a pickup with little weight on the drive axle. not too shabby tho for a grocery getter.
Terrific sound, tasty popcorn too. Sincere salute to American Muscle! Put it next to an Accura, Honda, Hyundai, Infiniti, Kia, Lexus, Mitsubishi, Nissan, Scion, Suzuki, or Toyota ... they will melt down completely, just melt to the ground. Vanish in shame, disappear in defeat. Kudos my friend. Well done.
what a hell of a machine. just lined up a merlin hardcore 572 for my 68 chevelle. I'm abit nervous on if it will fit without to many complications. Absolute awesome car with one hell of a donk
That's the oil pan I was thinking of. I knew linkage was a problem, cool that you got it too fit. I was reading the thread over on Chevelle forum about the tall decks under the stock hoods. Cool deal.
@paddoww Thanks. I luv the sound too. In addition to having a hair over 800 HP, this big block has lots of torque. Not only does the torque peak @4,000 RPM come in at 775 FT/LBS, but @3,000 RPM it's already at 715 FT/LBS and it stays above 700 FT/LBS from 3,000 RPM to 5,000 RPM. You sure won't do that with any smalblock engine unless you use a generous supply of nitrous oxide, or a means of forced induction.
I my self know that a 632 is big time not trying to run it down I have first hand knowledge of how fast it can break loose. I have seen so many go bad when on the streets trying to impress people. I'm sure you know how to feather the gas I don't drive anymore. Just don't ignore the signs of it getting loose. Oh man it's beautiful killer car .
ok Ron, I'll heed your warning about that. I hear what you;re saying. I've had some close calls with lesser cars in the past. I've learned that we have to respect the power under the hood, because it sure isn't going to respect us. I also do not ever engage in organized street racing. There are too many things that can go wrong
@OSH313 Thankyou for the compliment about my car. I'm still working on it to get it completed. it's been a lot of hard work, and it's been very expensive too. Compliments like yours help to keep me motivated to finish this project.
Plenty of builders make 632 CID engines. Its made from an aftermarket block which has thicker cylinder walls, so that you can take the bore safely out to 4.600" & it has a tall deck like a truck block which has a 10.2" deck height, so that the maximum stroke can be brought up to 4.75" but it really depends on how much money you want to spend, & if you want to fit it underneath a factory stock hood, because Sonny's now makes a 1005 CID engine, but that's about $90K & wont fit under a stock hood
I do use an air cleaner, & that is from that same place you've mentioned. Universal spinners. I had them fab a 2" drop in the base with a 16" overall diameter since the 16" dia. is needed for the 4500 series Holley Dominator carb. The Milodon 38811 oil pan was the best one I tried, but I still had to end up cutting the front cross member of the frame and using custom steering linkage pieces to clear it. I only had to cut the top of the frame about a 1/2" & then welded a steel plate on top of it
@matthew702917 No wheel tubbs. I didn't want that. I have P315/60/15 drag radials on there. I had the body place roll back the rear fenderlips as much as possible, and I ordered the aftermarket rear wheels with custom back spacing to fit the tires in there. The rear wheels are 15x10" wide with a 5.5" backspacing which is the maximum that can be used on 70-72 Chevelle. It puts the inner side walls of the tire within 3/4" of the outter frame rail wall. I also had to cut off the fenderlips
yes, agreed!!! And the 66-70 Chevelles, as well as the 63-72 Corvettes, 70-72 MonteCarlos, and the 67-73 Camaros are all some really great body styles too.
I was originally going to install this engine into a 70 Monte, but I then found the Chevelle I had been looking for. With a 70-73 Monte, the stock hood will likely not provide enough clearence for the single plane Dominator type intake manifold and carb that you'll need to run with a 632 CID engine. So you would need to use an aftermarket 2" cowl hood at the very minimum. And even that's only if you have a custom made air cleaner assembly with a 2" drop base like I did from universal spinners
gawd I just LOVE the sound of pure american muscle!!!!.....the loping of the cams back and forth...music to my ears!!!!; however its more like gallons to the mile., not miles per gallon LOL
You can go as big as 572 cubes on a standard deck height block, and as big as 632 CID on a tall deck block that's 10.2" like what I have, but now they have deck heights as tall as 12.1" and you can go 900+ cid if you have a reallot of cash to spend, but with the type of intake manifold a 700+CID engine will need, you'll never get it underneath a factory stock hood without cutting a hole in it or getting one of those big boxy looking 4-6" aftermarket cowl hoods to fit everything in.
Thanks DT. I can appreciate your comments. I'm not a big MOPAR fan either, but I also love seeing a 70 or 71 Hemi Cuda now and then, since they're really nice body styles.
@lluwd Thankyou. I really appreciate your viewpoint on that. It's because of that same viewpoint that I've kept the body of this car looking factory stock with the one minor exception being that I trimmed the underside of the rear fender lips back in order to fit the widest tires possible. But that isn't even anything that can be seen without having to lay on the ground and looking up inside there. The drivetrain & suspension have been heavily modified for the power level but the body is stock.
I thought I remembered some carb guys talking about using those MSD ignition boxes hooked up to their computers to program their timing curve. I really should learn more about the old school stuff. Sometimes I'm blown away by how much timing some guys are running on these street engines with pump gas. They are just to different beast. I want to buy my dad either a Chevelle or old Buick GS and I dont want to switch to LS/EFI unless I have to, I want to keep its soul intact.
@LordMMX66MHz The two things to be concerned about are the height of the intake manifold that's needed, and the depth of the front of the oil pan used to accomodate the massive 4.75" stroke of these engines. In a big truck like a suburban, you have plenty of hood clearence so the intake manifold height wouldn't be an issue. But the depth of the front of the oil pan can create issues with the frame crossmember clearence and the steering linkage clearence. I used a Milodon oil pan
@Mr84chvy Thanks for the kind words. And yes you're right that some people cannot handle the power, but that's mostly because they don't respect the power under the hood, and they overlook the fact that this power is NOT going to respect you. In one of Clint Eastwood's movies in the 70's(Magnum Force) in which he played the character "Dirt Harry" he had a line that he said to himself all through the movie"A man's got to know his limitations" and that is true when behind the wheel of a fast car.
I think those heads would be a good choice since they have the 345 cc intake ports. IMO with a street 632 CID engine, you'll want the intake ports of the heads in the 345-360cc range, the intake valve diameter at 2.30"-2.35" , the dur@.050 cam spec in the 270 degree range, a 3.55-3.73 rear gear ratio, 29"-30" tall rear tires, a 3.5" diameter exhaust with 2 1/8" diameter header primary tubes and 3.5" diameter collectors. And don't skimp on the rear end either by throwing junkyard parts into it.
@davejoshmom1 that's a good price. Horsepower costs money. It's a matter of how fast you want to go, and how deep your pockets are. The engine expense isn't the whole picture either. For instance, you can't just throw 800 HP under the hood, and expect that the rest of the drivetrain is going to take all of that power any longer than a month or two without being destroyed. You then need to spend more money on a beefed up suspension, transmission, torque converter, and rear end too.
@evhgl87 I think the dynamic CR is 8.65:1 and the static CR is 10.5:1 350cc ports on the heads, 2.30" intake valves, 1.88" exhaust valves. 6.7" H-beam rods with L-19 bolts, 4.6" bore, 4.75" stroke, forged flat top coated Mahle pistons with Total Seal gapless rings. Callies forged crankshaft. Lunati solid roller cam dur@ .050 is 268/271 (int./exh.) and total lift with 1.7:1 rocker ratio is .705"/.708" (int./exh.) 800 HP@5,900RPM and 775 ft/lbs torque@4,000 RPM.
it's really hard to get a muscle car in Europe, (Britain in my case) for various reasons, the insurance on one of those would be pretty impossible to handle and the fuel here costs over $2 a litre for regular 95... A V8 Jag costs less than 4 grand to buy but then you can't insure or run it let alone tune it! You guys can have guns and big engined cars, i want to move in there! lol
@techguyreview one of the biggest available, and certainly the biggest that will possibly fit underneath the factory stock cowl induction hood. And it was challenging for me to fit it under the hood. That's with a 3.5" tall air cleaner element and a custom made 2" drop base.
@DrMMHMD YES!!! this car is rowdy for a street motor. im sure that cam is well in the 250s or maybe 260s in duration. however the bigger the motor the more duration you can apply. my 496 has a cam that is 248/258 it will make its power peak at about 6200 . the bigger the motor in general you dont have to turn it hard to get big numbers , but when you make a high turning big inch motor, you better buy some depends
Thanks for the comments. As far as Mustangs, no thanks. The only ones I like are the 67 Fastback Mustangs. But I'm mostly a Chevy guy because I like the old Chevy body styles the best. A blower sticking outta the hood would go completely against my goal for this car. Which is to put as much horsepower and torque under the stock hood without having to use race gas, nor rev the engine to the moon. The power peak of 800 HP of this ride comes in by 5,900 RPM. No holes cut in the hood for me.
@Fleabiscuit21 the color is the original GM code #17 which is Shadow Gray and it's PPG code #32604 PPG used to call it "Pewter Gray" but it's the same color. "Shadow Gray". For the hood and trunk lid stripes I bought a stencil kit from a place on thenet called Stencils & Stripes and the body/paint guy told me that it was real easy to use and came with fantastic instructions that were a big help. The stripes came out real good, so I highly recommend that stencil kit.
@Baseballstud5964 and the answer is...PUMP gas...like the stuff you get at almost any gas station pump. Yes, 93 octane. The motor sounds like that, because it's a 632 cubic inch monster, has a fairly big camshaft , and also has open headers in this video. Like I've already stated, it has a static compression ratio of only 10.5:1 so it will run on 93 octane all day long on the street and at the dragstrip too. It was run on the dyno with 91 octane gas, and made 800 HP@5,900 RPM.
I have $17,000 in the engine. It's a crate engine, and you can buy 632 CID crate engines ranging from pump gas 800 HP versions to 1,200 HP race gas versions from $11,000 to as much as $30,000 but if I had to do it over again, I wouldn't have purchased a crate engine at all. I would've had it built by a reputable builder who builds one engine at a time by himself. One place that comes to mind is Lewis Racing engines owned by Mike Lewis. He pays much more attention to detail than any big place
@procharged70cutlass Yes, you're correct on that. The cam I have is a solid roller from Lunati originally designed for circle track 468 engines and is also used for some bracket drag racing. And yes, you're also correct that this cam has a .700+" lift at the valves, and that in a smaller engine, it would be quite radical for the street. The heads I have on this engine are middle of the road. Nothing that great. Just Merlin III aluminum 350cc heads with 2.30" intake valves. I haven't run it yet
If you want to build your own high horsepower engine buy a "Dart" engine, they're really high performance and not even that expensive. The engine of theirs that I would go with would be the 454 bigM sportsman block, with their high performance aluminum oval port heads, all together it adds up to $5500 and comes stalk with 500hp and is rated for 1200hp. It sounds like a sweet deal to me.
@mean70632 Sweet, probably a good idea anyway since that is one of rusts favorite places. I am thinking of cutting mine out just because this is the 3rd year I've had rust start around the rear wheels. And I took it down to bare metal each time and grinded the rust out. However I only have P275/60r15's hehe.
@charg2456 Being street legal merely requires a full exhaust with tailpipes over the axle tubes, mufflers, head lights, tail lights, brake lights, brakes, horn, windhsield, turn signals, seatbelts, & DOT tires.You can run a 2000 HP car on the street if you have the money to build it. Ofcourse that would require an engine needing to be run on 110 or 118 octane race gas costing up to 12 dollars per gallon. But this car has a pump gas engine.
@gigow22000 Then they might be running the Sunoco 100 unleaded gas which is legal for any gas station to sell at the pump and legal for anyone to pump it directly into their street cars since it doesn't contain lead (as you've stated). But very few stations have enough of a demand for 100 octane unleaded gasoline, so that's why it's rarely seen being offered anywhere. As far as I know, 100 octane is the most you can get without lead in it. All the 110,112,114,117, &118 octane fuels have lead.
That was the one I was thinking of the 6AL. I love the 70 chevelle's like I said those are my favorite but the 71-72 doesn't do much for me and the GS's look sort of similar to the 70 and since they use the same chassis there are plenty of parts for them, plus you don't see many of them. I really just want to get something from that era for my dad, so we can work on it together and go to shows together. He likes my car, but we both agree we'd like to keep it old iron if we can.
@BrantMOB Thanks. Yep, you're right that anyone who knows anything about fast cars is going to pick up on some things as soon as they hear this car run. But like you said, those tuner boys are clueless, so it's much easier to be stealth in front of them.
Boy do i miss the days of hearing that, that is music to my ears, i had that same car.
Thanks guy. My goal was to make it as powerful as possible, while still operating on 93 octane pump gas alone, remaining naturally aspirated, (no power adders nor forced induction) & keeping the factory stock body & the stock hood since I never liked those big ugly boxy looking 4" & 6" fiberglass cowl hoods.

That won't work because a good V8 sound is the best sleep ASMR ever.

I only had to cut the top of the frame about a 1/2" & then welded a steel plate on top of it
@matthew702917 No wheel tubbs. I didn't want that. I have P315/60/15 drag radials on there. I had the body place roll back the rear fenderlips as much as possible, and I ordered the aftermarket rear wheels with custom back spacing to fit the tires in there. The rear wheels are 15x10" wide with a 5.5" backspacing which is the maximum that can be used on 70-72 Chevelle. It puts the inner side walls of the tire within 3/4" of the outter frame rail wall. I also had to cut off the fenderlips
yes, agreed!!! And the 66-70 Chevelles, as well as the 63-72 Corvettes, 70-72 MonteCarlos, and the 67-73 Camaros are all some really great body styles too.
beast motor , i wanna put one in my '71 Monte wicked ride! man
Nice to see somebody still uses a Holley
thats one badass chevelle..wish this engine was on gran turisom 5
Oh and thanks a lot for all the info, ive been misinformed like you wouldn't believe.
I was originally going to install this engine into a 70 Monte, but I then found the Chevelle I had been looking for. With a 70-73 Monte, the stock hood will likely not provide enough clearence for the single plane Dominator type intake manifold and carb that you'll need to run with a 632 CID engine. So you would need to use an aftermarket 2" cowl hood at the very minimum. And even that's only if you have a custom made air cleaner assembly with a 2" drop base like I did from universal spinners
gawd I just LOVE the sound of pure american muscle!!!!.....the loping of the cams back and forth...music to my ears!!!!; however its more like gallons to the mile., not miles per gallon LOL
holy fkn shit one of the baddest sounds coming out from that chev :D beautifull
That thing eats tuners for breakfest, exotics for lunch, ford for dinner, and mopar for desert!
You can go as big as 572 cubes on a standard deck height block, and as big as 632 CID on a tall deck block that's 10.2" like what I have, but now they have deck heights as tall as 12.1" and you can go 900+ cid if you have a reallot of cash to spend, but with the type of intake manifold a 700+CID engine will need, you'll never get it underneath a factory stock hood without cutting a hole in it or getting one of those big boxy looking 4-6" aftermarket cowl hoods to fit everything in.
Thanks DT. I can appreciate your comments. I'm not a big MOPAR fan either, but I also love seeing a 70 or 71 Hemi Cuda now and then, since they're really nice body styles.
@lluwd Thankyou. I really appreciate your viewpoint on that. It's because of that same viewpoint that I've kept the body of this car looking factory stock with the one minor exception being that I trimmed the underside of the rear fender lips back in order to fit the widest tires possible. But that isn't even anything that can be seen without having to lay on the ground and looking up inside there. The drivetrain & suspension have been heavily modified for the power level but the body is stock.
I thought I remembered some carb guys talking about using those MSD ignition boxes hooked up to their computers to program their timing curve. I really should learn more about the old school stuff. Sometimes I'm blown away by how much timing some guys are running on these street engines with pump gas. They are just to different beast. I want to buy my dad either a Chevelle or old Buick GS and I dont want to switch to LS/EFI unless I have to, I want to keep its soul intact.
@LordMMX66MHz The two things to be concerned about are the height of the intake manifold that's needed, and the depth of the front of the oil pan used to accomodate the massive 4.75" stroke of these engines. In a big truck like a suburban, you have plenty of hood clearence so the intake manifold height wouldn't be an issue. But the depth of the front of the oil pan can create issues with the frame crossmember clearence and the steering linkage clearence. I used a Milodon oil pan
No replacement for displacement very accurately represented here...
beautiful car man great job!
Those damn runners on the headers are bigger than the whole exhaust on my car, wow.
Hi I owned 455 71 buick but thats chevy rock! 632 yeah grazy cubic! nice work!
@Mr84chvy Thanks for the kind words. And yes you're right that some people cannot handle the power, but that's mostly because they don't respect the power under the hood, and they overlook the fact that this power is NOT going to respect you. In one of Clint Eastwood's movies in the 70's(Magnum Force) in which he played the character "Dirt Harry" he had a line that he said to himself all through the movie"A man's got to know his limitations" and that is true when behind the wheel of a fast car.
That is a lovely noise.
that is one tough chevelle chevy power all the way
Nice ride and nice work William, I'm a die hard Ford guy but that is sweet. Happy Holidays.
yes please. it sounds fricken amazing!
I think those heads would be a good choice since they have the 345 cc intake ports. IMO with a street 632 CID engine, you'll want the intake ports of the heads in the 345-360cc range, the intake valve diameter at 2.30"-2.35" , the dur@.050 cam spec in the 270 degree range, a 3.55-3.73 rear gear ratio, 29"-30" tall rear tires, a 3.5" diameter exhaust with 2 1/8" diameter header primary tubes and 3.5" diameter collectors. And don't skimp on the rear end either by throwing junkyard parts into it.
look at nr1 cylinder go!! awesome car.. One day I`ll have something like this..
Wow I'm blown away....NICE !
@bmgbilly awesome! bc it looks about the same size as a Chevy 572. and i have one still in the crate at my shop
@davejoshmom1 that's a good price. Horsepower costs money. It's a matter of how fast you want to go, and how deep your pockets are. The engine expense isn't the whole picture either. For instance, you can't just throw 800 HP under the hood, and expect that the rest of the drivetrain is going to take all of that power any longer than a month or two without being destroyed. You then need to spend more money on a beefed up suspension, transmission, torque converter, and rear end too.
@evhgl87 I think the dynamic CR is 8.65:1 and the static CR is 10.5:1 350cc ports on the heads, 2.30" intake valves, 1.88" exhaust valves. 6.7" H-beam rods with L-19 bolts, 4.6" bore, 4.75" stroke, forged flat top coated Mahle pistons with Total Seal gapless rings. Callies forged crankshaft. Lunati solid roller cam dur@ .050 is 268/271 (int./exh.) and total lift with 1.7:1 rocker ratio is .705"/.708" (int./exh.) 800 HP@5,900RPM and 775 ft/lbs torque@4,000 RPM.
love the stripes on the 632
Jesus fuck, what did I just witness, UNREAL car!
it's really hard to get a muscle car in Europe, (Britain in my case) for various reasons, the insurance on one of those would be pretty impossible to handle and the fuel here costs over $2 a litre for regular 95... A V8 Jag costs less than 4 grand to buy but then you can't insure or run it let alone tune it! You guys can have guns and big engined cars, i want to move in there! lol
@techguyreview one of the biggest available, and certainly the biggest that will possibly fit underneath the factory stock cowl induction hood. And it was challenging for me to fit it under the hood. That's with a 3.5" tall air cleaner element and a custom made 2" drop base.
its a tall deck merlin block with a single carb and conventional heads. i think its awesome in that car.
@mean70632 hahah Yeah man, I hear ya. I built a 92 camaro a while back. Gas was $1.60 and I couldn't afford that car back then. Great ride man!
@DrMMHMD YES!!! this car is rowdy for a street motor. im sure that cam is well in the 250s or maybe 260s in duration. however the bigger the motor the more duration you can apply. my 496 has a cam that is 248/258 it will make its power peak at about 6200 . the bigger the motor in general you dont have to turn it hard to get big numbers , but when you make a high turning big inch motor, you better buy some depends
I spent the money on lemons...well worth it ...take the tip & get em coated also..
I love how the timing light is just sitting there hooked up and going off.. hahaha
Thanks for the comments. As far as Mustangs, no thanks. The only ones I like are the 67 Fastback Mustangs. But I'm mostly a Chevy guy because I like the old Chevy body styles the best. A blower sticking outta the hood would go completely against my goal for this car. Which is to put as much horsepower and torque under the stock hood without having to use race gas, nor rev the engine to the moon. The power peak of 800 HP of this ride comes in by 5,900 RPM. No holes cut in the hood for me.
@Fleabiscuit21 the color is the original GM code #17 which is Shadow Gray and it's PPG code #32604 PPG used to call it "Pewter Gray" but it's the same color. "Shadow Gray". For the hood and trunk lid stripes I bought a stencil kit from a place on thenet called Stencils & Stripes and the body/paint guy told me that it was real easy to use and came with fantastic instructions that were a big help. The stripes came out real good, so I highly recommend that stencil kit.
Sweet Jesus! It's an eight cylinder symphony!
Oh my God! That think sounds so amazing
@Baseballstud5964 and the answer is...PUMP gas...like the stuff you get at almost any gas station pump. Yes, 93 octane. The motor sounds like that, because it's a 632 cubic inch monster, has a fairly big camshaft , and also has open headers in this video. Like I've already stated, it has a static compression ratio of only 10.5:1 so it will run on 93 octane all day long on the street and at the dragstrip too. It was run on the dyno with 91 octane gas, and made 800 HP@5,900 RPM.
I have $17,000 in the engine. It's a crate engine, and you can buy 632 CID crate engines ranging from pump gas 800 HP versions to 1,200 HP race gas versions from $11,000 to as much as $30,000 but if I had to do it over again, I wouldn't have purchased a crate engine at all. I would've had it built by a reputable builder who builds one engine at a time by himself. One place that comes to mind is Lewis Racing engines owned by Mike Lewis. He pays much more attention to detail than any big place
love the riveria in front too haha
@procharged70cutlass Yes, you're correct on that. The cam I have is a solid roller from Lunati originally designed for circle track 468 engines and is also used for some bracket drag racing. And yes, you're also correct that this cam has a .700+" lift at the valves, and that in a smaller engine, it would be quite radical for the street. The heads I have on this engine are middle of the road. Nothing that great. Just Merlin III aluminum 350cc heads with 2.30" intake valves. I haven't run it yet
If you want to build your own high horsepower engine buy a "Dart" engine, they're really high performance and not even that expensive. The engine of theirs that I would go with would be the 454 bigM sportsman block, with their high performance aluminum oval port heads, all together it adds up to $5500 and comes stalk with 500hp and is rated for 1200hp. It sounds like a sweet deal to me.
@mean70632 Sweet, probably a good idea anyway since that is one of rusts favorite places. I am thinking of cutting mine out just because this is the 3rd year I've had rust start around the rear wheels. And I took it down to bare metal each time and grinded the rust out. However I only have P275/60r15's hehe.
@charg2456 Being street legal merely requires a full exhaust with tailpipes over the axle tubes, mufflers, head lights, tail lights, brake lights, brakes, horn, windhsield, turn signals, seatbelts, & DOT tires.You can run a 2000 HP car on the street if you have the money to build it. Ofcourse that would require an engine needing to be run on 110 or 118 octane race gas costing up to 12 dollars per gallon. But this car has a pump gas engine.
@gigow22000 Then they might be running the Sunoco 100 unleaded gas which is legal for any gas station to sell at the pump and legal for anyone to pump it directly into their street cars since it doesn't contain lead (as you've stated). But very few stations have enough of a demand for 100 octane unleaded gasoline, so that's why it's rarely seen being offered anywhere. As far as I know, 100 octane is the most you can get without lead in it. All the 110,112,114,117, &118 octane fuels have lead.
Sweet sounding motor and great throttle responce
That was the one I was thinking of the 6AL. I love the 70 chevelle's like I said those are my favorite but the 71-72 doesn't do much for me and the GS's look sort of similar to the 70 and since they use the same chassis there are plenty of parts for them, plus you don't see many of them. I really just want to get something from that era for my dad, so we can work on it together and go to shows together. He likes my car, but we both agree we'd like to keep it old iron if we can.
what a fuckinn beast. now that's some serious heavy chevy right there!
@BrantMOB Thanks. Yep, you're right that anyone who knows anything about fast cars is going to pick up on some things as soon as they hear this car run. But like you said, those tuner boys are clueless, so it's much easier to be stealth in front of them.
that is awesome that it runs on pump gas
hahaha I started to doze-off watching this, man that sound can sure put me to sleep :) I love it.
