Found this in Chevy Teck Tips: 7.4 Liter Gen VI (454 ci) RPO L19/L29: 290 net hp at 4,000 rpm (trucks only) The Vortec 7400 featured more refinements including the use of MPFI (multi-point fuel injection) and hydraulic roller lifters: small oval (“peanut”) port cast-iron heads, four-bolt main caps, cast-iron crankshaft. Available in trucks only from 1996 to 2000.
Had peanut port heads on my 489 stroker. Gen 5. Had the guides cut for positive seals and more clearance and 7/16 screw in studs. Ran a .566 lift, flat tappet cam in my jet boat. Ran beautiful. Have brodix heads now.
I have almost this identical set up with peanuts but I’m on e85 and run a .572/572 110lsa roller cam I had with 9.8/1 compression in a 3000lb Monte Carlo. Pulls the front tire and runs 11.3s all day.
Port and valve them or get aftermarket heads. This is Gen 5, the last Mass produced BBC was Gen 6 454 and 496. Which are heavily revised from the mark 1
I am going to be rebuilding a 1986 454 from an RV for a truck that will be towing a two car trailer with two rock crawler Jeep XJs. From everything I've seen in your videos (and others) I think I am going to keep it stock and add a 268 cam and keep the peanut port heads. I already have a set of long tube headers that came with the truck so I'll be using those as well.
The only Big Block Chevy I have ever had experience with was a 8.1 in a Camper ( I think) So this video is interesting to me . There are a lot of Big Block fans in my area .
It would probably work good with a centrifugal blower, the rising boost curve would nullify some of the choke that happens from the crappy ports. Any boost is good boost.
@@timothybayliss6680 absolutely.....boost is life. A custom cam that will get everything out of the peanut ports plus boost could yield a 1000hp plus outrageous torque.
I’ve got a 10.5:1 oval port . It stock shifted th400 @4500 and fall short of its open value. 3rd/2nd drop . Nothing less than 5600 up - to 75-8k Tears 275s up for breakfast And cracked the 400 transmission case. … having fun. 😇🤕🤠 eh 10 more years to wait . That’s life .. might as well restore it right .

That 200lbs weight difference is noticeable especially when located at the front of the vehicle..
Thanks Richard. The profiler heads are a new test i think. Its a nice test to see. After your last peanut port test video with the 212/218 cam I was hoping you were gonna throw some AFR 265 heads on it. Seeing where that combo peaks vs the peanut port would be interesting i think. On the street it seems like having as much as you can at low and mid power ranges with a peak at around 5200 would be ideal. The lower rpm would help increase the life of the engine too.
@@cargotoolshop5319 a 100 hp gain with a 212 duration cam? On one of Richard's videos he uses peanut ports with bigger valves and mild porting I think and a 245 duration cam. When he put afr 265's on I believe there was a 70 horse gain. If my understanding is correct a smaller cam would have less of a gain. It makes me wonder if a 100 is possible.
Seems like short of headers and having a torker 2 single plane vs dual plane I should be around the same with my oval ports. Thank you for these videos. This 454 will work perfect for my truck.
Can you do one with the mark 4 if possible because I know they are hard to find but im trying to see what I can do for a budget build for a street build
Hey Rich,,, I think I got a good show for you to do and reasonable... How about one day you do a stock exhaust manifold test to see which one makes the best power for the SBC,,, I believe it's about 3-5 different style of manifolds and I'm sure it's guys that want to know what's the best flowing stock manifold for the SBC... I would even do it on a mild to wild SBC,,, not a stock motor... But great info for the big blocks I'm doing one as we speak💪🏾💪🏻💪🏾💪🏻💪🏾💪🏻💪🏾💪🏻💪🏾
Any chance of doing a marine application build I have two late 80s 454s in my boat and they need to be freshened up I would love to see what could be done on a budget with a peanut Port heads
That’s exactly what I’m doing! Just saw your comment. Mark IV four bolt main, stealth intake, 268h cam, and FAST fuel system. Was originally going with peanut ports, but then found some 781s. It’ll be a while before it’s done, but I’m confident it’ll perform!
although i have a gen IV in my Monte, i was happy to see you test the gen 5 .. the flat tops im dealing with are killing me but it is strickly a street car. i dont want to pull the pistons. ive been thinking about doing Vortex L29 heads to pump up the CR but is it really worth it ?
Great channel Richard , I've asked before and not sure if you answered but I have an intake the Bryce ported for me in 2008 , whatever became of him ? It's a Victor Junior that I have on a twin turbo 555 that I'll take to my grave as it fits under my flat 79 Blazer hood .
Two questions 1.have you done this test with the gen6 heads vs peanut port and 2.how about a test adding nitromethane to pump gas like back in the early days,thanks love the videos keep it up
Can you do a detailed hopup vid like this for the Gen 6? The g6 heads have big lumps in the intake ports on one side of the guide, which I really want to grind out. Any tips?
After the third test, it would've been nice to see what a set of ported peanut port heads would do...probably would've gained torque down low and easily tacked on 75+ hp up top (525hp minimum, with the same ).
Yes!! I wanted to see how far you could go with stock peanut's, keep increasing cam until it was worthless to go further. Then start with a mild port a guy could do in his garage, and move up a little from there. It always seems to end after trying basically nothing, to putting on a set of $1,245,000 aftermarket heads nobody can afford, and showing how it gained 3,547hp over the stock heads!!! What gives with that stuff? I mean, don't call these things "little guy" builds, then put "big guy" money into them!! Let's see how far it can go with stuff the average bubble gum chewer can toss at it!!
@@youcanbesmartaskhow3857, each cfm can be worth 2 hp, it's straight forward to add 40 cfm to the peanut port head. With the right cam, that can be worth 80 hp.
Curious as to what the compression was with the last version of the PP heads. That engine with 500 plus torq at 2500 rpm would be a blast to drive on the street, dont even need a high stall converter.
Couldn’t you have stayed with the second cam duration but increase the lift to the spec for the final cam and made the same hp?? Thanks Richard for the great video as always.
I would have liked to see just a little bigger camshaft than the xe268. Then maybe bigger valve upgrade to the peanut port heads.....just to see what would happen. 450hp and 550ft.lbs. of torque would be a great street engine.
Yeah kinda pissed me off when stopped after the 268 baby cam. Not too difficult to change springs when you got the tools there and on dyno etc. I want to see what a comp 292 Magnum cam will do.
Richard, thanks for this video. Before you went to the Profiler heads and bigger cam/intake. What do you expect would have happened if you swapped the Gen V Peanut port heads with the stock Gen VI 100cc Oval port heads? I have a Gen V block and 12cc domed pistons, and a set of refreshed Gen VI heads. Edelbrock Air Gap manifold. I want a low end torque engine to run on pump gas. For towing/hauling on my 1950 Chevy COE Truck. 4L80E. 5.13 gears and 40" tall super single semi tires. Not sure I can run 87 octane gas because I believe my C.R. would end up at about 9.8:1 Would have like to have seen what that short block would have done with the Gen VI heads and the same Comp XE268H 515/520, 224/230, 110 cam.
@@richardholdener1727 Richard, thanks for the reply. I have watched all your videos. Issue is that all your Gen 6 videos have roller cams. Nothing i saw was close to the XE268H
Question : When installing new a cam and lifters for Dyno testing , do you "break in the cam " or just warm the engine up some and do a Dyno pull ? I ask out of curiosity , not being critical at all .
I would have liked to see how far the peanut ports could go. Anyone can spend $837,000 on a set of aftermarket heads and make power, lets see how far we can go with the crappy peanut ports!!! Don't spend $372,000 on head porting either, just mild stuff a guy could do in his garage. I'm curious what a 250/260 @ 0.050 cam would do with these heads? Would it reach 500hp? What if we bumped the compression up to 11:1 or 12:1? Can it make it passed 500hp? If only I had a dyno!! But then again, if I could afford a dyno, I'd be building 632ci big blocks with roots blowers on them and putting them in my full chassis/fiberglass drag car!!
If I was to stroke my gen V to 496 keep my peanut port heads, dual plane intake, 750 carb, long tubes, do you think it will make 500 ftlbs at 2k? I've got a 1984 gmc crew cab with a 4 speed and a gen V 454 that I have to rebuild.

Do all gen v motors have those valve covers? I have a 1988 Chevy R30 with a 454. It has the older style valve covers with the bolts around the outside of the cover. Where on the motor can I find the identification numbers?
Hey Richard, I’m getting ready to start on my first truck build and I’m 16, I have a gen V 454 in a 89 k3500 which is EFI. Could we maybe see the power difference between an efi 454 and a carb 454? If not a video, could you help me out on deciding what to throw on to make most hp/ torque?
I was wondering what could I do to a 1993 Chevy suburban with 454 to get more power for pullin a travel trailer and still be reliable love your videos thanks
Don't take my word for it, but Ive heard of people putting an "RV" cam into their stock Gen V to make a little extra power for towing. I'm following someone's junk Gen V build and they put the Summit K1300 camshaft in.
for a 454 yes. for a 496 the AFR 305cc heads do really good rectangle port with a weiand dual plane retangle port the port opneing on that head and the 8018 intake are exactly the same size. ive seen videos of those making 650hp...

Do all gen v motors have those valve covers? I have a 1988 Chevy R30 with a 454. It has the older style valve covers with the bolts around the outside of the cover. Where on the motor can I find the identification numbers?
these have the same bolt pattern, these were gen 6 covers

Pp heads rule. When no other heads are around.
Who’s flat tappets did you use ? Did you have any trouble with them ?
comp-test was done long ago
Hey Richard, I’m getting ready to start on my first truck build and I’m 16, I have a gen V 454 in a 89 k3500 which is EFI. Could we maybe see the power difference between an efi 454 and a carb 454? If not a video, could you help me out on deciding what to throw on to make most hp/ torque?
SWAP THE TBI FOR A DUAL PLANE AND CARB-IT WILL BE 40 HP BETTER
Richard Holdener thank you so much man! I have one more question, what would be the first mod you would put on a bone stock 454
@@garrettraymond6258 cam and springs and or headers.
Lost where you were going thought we were going to see the limitation of peanut port head what would happen if you'd put on a 496 storker
other peanut port vids up
What was the stark compression ratio before the piston change at what was it after
LESS THAN 8-THEN 9.4
@@richardholdener1727 thank you
What dome piston did you use with the XE268 cam .
18-22 CC DOMES WORK WELL
I was wondering what could I do to a 1993 Chevy suburban with 454 to get more power for pullin a travel trailer and still be reliable love your videos thanks
Intakes aren't usually made for p p heads
What is the BEST overall cam to upgrade to for power in a stock stock everything Gen5?
something mild
Don't take my word for it, but Ive heard of people putting an "RV" cam into their stock Gen V to make a little extra power for towing. I'm following someone's junk Gen V build and they put the Summit K1300 camshaft in.
Best mods for a gen 5 mercruiser old son ? Retain stock heads.
The AFR 265 heads seem like they're about the best head you can get for the street. Would you agree richard?
for a 454 yes. for a 496 the AFR 305cc heads do really good rectangle port with a weiand dual plane retangle port the port opneing on that head and the 8018 intake are exactly the same size. ive seen videos of those making 650hp...
THEY WORK WELL
You also had E3 spark plugs. Those are worth 200hp
AT LEAST
Is there a cheaper piston i can use to get these results probes are high.
yes-any piston will work
It says online that manifold will not fit peanut port heads, sure they fit?
it bolts right on-ports are mismatched though
@@richardholdener1727 does it matter performance wise if the ports are mismatched? thanks for your reply im looking to do the same exact build to my genV
The question is: How well would the engine have run if instead of swapping to the expensive heads you had used the Gen 6 heads???
LOTS OF GEN 6 STUFF UP
I want to duplicate this build in my 1990 SS but use a comp 260-AH computer cam 396 325hp heads #3872702 .
Only prob these heads dont have a temp sensor location on left head.
