410 cubic inch Gen II LT1 On The Dyno (409LT1)
zhlédnutí 10KPřed měsícem
What? A 410 LT1? This is a 4" stroke, 4.040" bore LT1 which makes 410 cubic inches displacement. Lots of details in the video. Dyno pulls at the end. Enjoy. All comments encouraged. NOTE: the 1st dyno pull sheet I inserted was actually the 3rd dyno pull sheet. Sorry, I mixed that up in the final editing. Note that when you stroke a small block chevy using a 4" crank you'll have a 408 ci engine ...
Rebuilt Engine On The Dyno. Low Oil Pressure!
zhlédnutí 681Před 2 měsíci
Had to cut short an engine dyno session a few weeks ago. Oil pressure was only 50 psig at high rpm. Spoiler Alert: The reason for the low oil pressure ended up being a week or damaged oil pump relief spring. In this video I try to explain the troubleshooting process that led me to that conclusion. I did make a mistake in the video where I said this M155 pump is high pressure. It is not. It is s...

Doug Rippie LT1 383 on the engine dyno

Full dyno session of the DRM LT1-383. This engine started life as a 1995 Corvette LT1-383 stroker built by Doug Rippie Motorsports. The engine is quite similar now as it was then except for being a 4.040" bore and flat top Mahle piston with the 1mm ring package. Same heads and same cam. I hear the motor made 450 hp back in 1995.

It's been a while since I had a customer engine on the dyno. Jim's water brake has been on the fritz and it has been repaired. All is well with the dyno. Now my Holley 850 carburetor has been sitting on the shelf for (how long?) a long time. Today went pretty well but the carburetor was spitting fuel at low load and low rpm. The longer we ran the engine the better it got but it never totally "f...

Did you get the idle down by adjusting the TB screw?
Hello there new subscriber here. Im looking to start my first build my goal is to build a mild performance lt1 with aluminum heads. And run a carburetor. Wish me luck. Ill be watching all your vids.
Well guess what i found Some one had built this engine and for some unknown reason Broke off the knubs that he is showing in this video I had no idea So now i have ordered a complete GM seal and housing kit and will use his procedure Thanks
How can i reach you on this seal install i have a 1989 350 new scat crank the new seal leaked and the second seal leaks I will try your alignment procedure I was not aware that the seal housing can move ?? hope this is not a dead web page ?
Im researching through the collections this is the video ive been searching for i have a 96 ss looking to build a forged 383 f1 blower motor i have a vault of questions. Looking forward to working with Mr. Karl.
Man Id love to have my engine rebuilt by you! I have a 93 corvette and I just pulled the engine from the car. Im nervous since this will be my first go at rebuilding an LT1 seems like you are living the dream!
That was a great shot
Ever find the issue?
Yes. the rumble was exactly what I had guessed. the engine rotating assembly was not balanced very well. The rebalance was performed and then all smooth. the car drives very well now. the owner is enjoying the car, (has been for a few years now). Thanks for asking and watching.
What heat sheilding did you use on the floor... i need some of that on my C4 vette
that is 4 or 5 panels per side of DEI-95503. Then hardware store screws with built in wide washers. The panels are sticky backed but I did not trust that the stick would stay.
What nice combination, got me thinking, appreciate you for this great info!
Why do they always make a simple thing sound so complicated to the point that you are more confused than ever ?
I hear ya! And if I do that, I try not to.
I bet that efi curve could have been improved.
Yes, agree. We did not spend time on that. (time and money)
Great video man! Where did you get those splayed 4 bolt main caps I want to do the same for my 95 lt1
Milodon small block Chevy splayed caps. Good stuff.
Hello Guys! I have a 91 Chevy Truck with a 2 barrel TBI Engine. When I rebuild this 350, can I add some Horsepower without switching to a Carburetor system? I only want about 350 Horses. What way should I go?
When’s the next vid drop on the 410? 😎😎😎💨💨💨
Probably not for quite a while. The owner still has to gather time and money to have it installed into his Pontiac Formula (My buddy Nabil will be doing the install). So probably when I do the street tuning for his car. A long time from now I think.
🎉🎉🎉
SPIT BLESS 😅
I did a complete gen1 top end conversion on my gen2 LT1 for my Chevelle, it ran 11.5s NA, fun setup and project. I converted it over to reverse cooling
I kinda like that idea. Thanks for mentioning that you did that and had success. There sure are a lot more choices for heads for Gen 1
This build will not last long enough to do anything with it.
Spoken from experience? Do tell -
That TQ Curve gets any flatter it will be a straight line.. HOLY COW! Nice build Carl !!!
,,,,,,,,,,,,,,,,,,,,,amazing camera work inside the cyl ; watching the piston and valves..................
Thanks.
How we cooling her?
The owner doesn't have anything out of the ordinary for cooling except the Meziere electric water pump and his stock fbody cooling system. That is usually all that is needed.
A custom In House porting of 210cc AFR Heads? okay
Yes. I agree. I did not recommend that. I do think that people have fun doing whatever it is that they think is fun and this customer really wanted the AFR's to be ported even more. To each his own. I've don't plenty of (worthless) mods in the past myself. Not to say the porting was worthless but very low bang for the buck.
Great music. Question on the lifters, do the GMPP come with the laser logos on them?
Yes. Exactly.
Is this to keep the all internal balance?
No. Not for that but this allows the use of less expensive and more available 2-piece rear main crank
@@EllweinEnginesi guess that is a valid factor but all internally balanced is added bonus (except 400). How much is seal adapter kit?
@@jacobnorth8642 I have not made these available yet for re-sale. I still have to put on one of my own engines and give it a good workout.
Nice work! Very meticulous and very patient with your builds.
Thanks
With E85 id be pushing customers into more compression. My 2017 Mazda Miata is 13:1 and runs on 93 Surely with newer fuels being better a E85 SBC withs lots of compression will run fine All motor Hondas are at 14:1 on E85
I hear ya. I'm going to switch to E85 for my personal impala SS with an F2 super charger. That will give me actual experience with E85 and tuning for it.
@@EllweinEngines The cooling effect also is what people forget not just being able to make more power. Its like having meth injection in a sort of way.
To bad Advanced Induction isnt doing SBC LT heads anymore Those cars and heads were fast from AI
Amen. Maybe some day? Their quality was top notch and their cam design was second to none.
@@EllweinEngines Absolutely fantastic and everything they touched for the LT1 stuff was FAST!
Put the pick up in the freezer overnight and it will go in without heating the pump
I'll try that next time. Thanks
pack it in dry ice for a quicker result? used to do that for injection molder bushings.
More compression and put it on E85.
Oh yea! 650hp plus maybe?
Less LSA probably make little more power. Nice build though for sure.
Less LSA probably make little more power.
Can u build me this same engine? I have a 96 Z28 but I want to use my stock intake manifold but port match it to the heads. Just need a price.
with the AFR heads? Yes can do. Good news is that that AFR began to offer the AFR 227 head for the LT1 once again. So anyway...the crankshaft is $3000 plus and the AFR 227 are??? lets say around $2700. Then Jesel shaft rockers $1800. It's adding up fast. Lets estimate $15,000 (or more after all the little things add up). But you can email me and I'll give an official invoice estimate. Karl@EllweinEngines.com
@@EllweinEnginesThat crank is not needed, heck @ 600hp a scat 9000 series would be plenty strong enough. I've seen people, many people run that horsepower level with bone stock 3.48" gm cranks, spraying them with nitrous. So really no need to drop 3k on a crank unless maybe your running boost at over the 1k hp level. I've only ever seen one crank actually break and that was from an 8-71 sitting on top of a 383 with like a pro comp crank in it and it broke the nose of it off.
Awesome build 👀💪
Thank you 🤗 Ty
I always hold my breath when I watch one of your dyno videos's. Lol
Yea, me too, but not for that it might make "the most power" but for it might blow up. :)
@@EllweinEngines Lol
Hey I need some advice if you have time. I bought an s10 that already has a 355 sbc, AFR 227 64 cc heads, single high rise intake, and a 650 carb on it. It falls a little flat up in the rpm range due to the flat tappet cam. The block is an old single rear main sbc. I originally wanted to go LS but don’t have the funds to completely swap everything over. What are your thoughts on going LT or L31 so I can get a hydraulic roller and keep the top end parts?
Many options but the 1st thing I though of was just doing a hydraulic roller conversion with your current sbc. You have the best heads definitely.
your carb is running out of air and falling flat 650 is 305 carb lol
@@alonzahanks1182 absolutely not. 650 Is just fine on a 355. I could step up to a 750 but it’s not going to matter with a cam that won’t carry past 6,000. Lol to you.
@@Gregoman89 im used to stock cams heavy duration loves more air period even made 305 get up and go but can only hit pedal 3/4 till it gets about 3000 rpm then i punch it all the way and all 350 trucks came with 850 Rochester only cam that didnt care about more air and fuel is 106 to 108 LSA tow truck or race car and that was old school pointed lobes with little duration I have 97 chevy lt1 with little 48 mm Throttle body the tb is what held it back on hp to 285 its actually 52 mm with 4mm idle air hole stock cam drilled it to 1/8th inch idle became 1100 at idle doable 1st gear topped out at 50 mph 1.5 to 2 sec 60 ft its now a 807 cfm tb goes to 65 mph in first and does 1.97 60 mph in about 120 feet in the time it did 60 ft it was 52mm 732 cfm it is 54.5 cfm 807 cfm at wot you are pulling vac if under carbed and 355 bore loves to make more HP and tork
An Isky 292 mega cam (flat tappet) will rip right up to 7k with no problem! And has a sound to die for!!
Nice engine. Certainly a good build. Nice horsepower. Thanks for sharing. Have a great weekend.👍
Thanks 👍 You too
This is a very unique and awesome build, love it , I’ve been wondering this for a while now , is the Gen ll SBC block stronger then the Gen 1’s ? And do you have a better chance on clearancing a Gen ll LT1 block for a 4 inch stroke then you do a Gen 1 block ?
To answer the Gen 1 vs Gen 2 block comparison...I guess some Gen 1 blocks are actually better than Gen 2 but most Gen 1 (older) are not as good overall. Recently built a customer's GMPP 383 gen 1 small block Chevy and it was as good as the GEN II LT1. The 400 SBC gen 1 is certainly better the Gen II LT1. I would guess that neither block has an advantage for clearancing. All mostly the same bottom of the block area. For help with the 4" stroke clearance then smaller rod journals are a big big help.
@@EllweinEnginessorry karl but from my experience the gen 2 blocks are much stronger, ive seen more problems with the deck cracking around the head bolts on the gen ones, especially the 400's once you push them hard nearing 4 digit levels. The splayed bottom end holds up pretty good its the decks and cyl walls we've always had problems with.
@@EllweinEnginesmy old man was using 400 blocks to make 700hp+ engines for dirt late model cars way back in late 80s early 90s. The last one he built for a friend still runs to this day. They actually used the 2 bolt blocks because the 4 bolt ones would wind up being weaker because not as much solid steel there. They were using extremely light crankshafts and internals so the force on the mains wasn’t as much as well. I’d imagine if it was heavier rotation the 4 bolt would be better.
@@stevenbelue5496Maybe it depends on the year and time era the blocks were casted? Id assume the gen 2 had better materials and some better metal vs older ones But Id guess maybe a current SBC1 from GM performance made and casted in recent times is as good? Not everything old is always good vice versa
@Thumper68 When it comes to the old 400 sbc blocks if you were running 400-500hp really didn't matter 2 or 4 bolt as with all gen 1 sbc's really, But if you start climbing to that 700-800hp mark the 2 bolt mains were the way to go, opposite with a 350 block.
So far your 383’s are the highest HP engines around for the LT1/LT4 I believe..
I’ve BEEN WAITING for this upload 😎👍
Man oh man Stevie...you tube has pushed this video and it may get as many views as yours (in a year or so from now). cool!!!!
Could you talk about how you modified the SBC single plane to the LT1 heads? My current 383 LT1 build has a single plane, and the clearance on those inner bolts is awful.
use short header bolts on those inner bolts… gives u a lot of extra room to get them in
That was it...the short header bolts. That was the only thing that fit there. But I also hand hogged the hole to give more bolt access. That actual manifold was machined for LT1 bolt access via Advanced Induction (for way back in the day) It was to match a cylinder head of theirs and they drilled and tapped the center holes to match the intake manifold so those center holes of the Gen 1 intake can be used. The other manifold bolt holes could be hogged out by hand if need be. TPV Productions has a good how to to make a Gen 1 manifold fit on a Gen 2 cylinder head (he does it by hand). czcams.com/video/MJ_xd2pJe70/video.htmlsi=X54mHKBVIp2FHPes
Interesting, I maybe have a different single plane intake, because currently I have to have the studs ran down into my heads, which are run almost flush with the intake, and then I put a nut on the very edge of the thread, then walk the stud back up. It’s a slow process, but my intake runners run so close to the LT1 holes that we couldn’t fit the stock LT1 intake bolts in there.
Luv get c4 vette LT1 engine rebuild by you Mr.ELLWEIN
cool. Thanks for your vote of confidence on my building skills
Great content
Thank you very much. Trying to give as much info as possible (and get the customer work finished at the same time)
Why a lt1 block? Not knocking just wondering…
Good question. I don’t really have a “good” answer. Only one advantage is that the engine goes right back into the car it came from and can be plugged right back into the factory harness (and tuned by a good tuner). There are so many other stronger combinations available for the money (and LS1 heads are in another universe compared to LT1 heads) but now sticking to the LT1 has become the "different and unusual". Almost refreshing to see an LT1 in and LT1 car.
@@EllweinEngines thanks for answering that makes sense
That new LT1 block they had at pri was badass, for gen 1 or 2, an aluminum version would be the shit.
This is an LT1 channel. That’s why!
Matching numbers block increases value but that’s a lot of cubes out of that block.
VERY respectable numbers on this 410 cid. Well done, Mr Ellwein!
Thank you very much. Hopefully you see the Rippie today
Beautiful work as always Karl.
Thanks.
Hey Karl are you coming to the Issca nationals this year???
Yes. See ya there.
Great video
Great video, I wanted to ask if you could please tell me if you are using the MPVI 2 to tune the lt1 pcm?
No not the HPTuners for “tuning”. Just for monitoring and data logging. I have to use JETDst for LT1 1996 and the better TunerPro for 1995 1994 (for dash tuning)
You Rock lol
