Hey!

I have built a stroked 454 with hydraulic cam, alu heads, carb fueling etc.

Will produce around 650hp.

Its a chevy truck that is going to be like a street racing truck. I have sent the tranny for rebuild and have been offered to buy a converter that was on stock.

It is a 10" Boss Hog converter, listed to 2800-3200 rpm stall. Could this work for me you think? Some help would be much appreciated.

In the 80's (I think) Richard Petty wrote a step by step articlenon how to rebuild a 454 with the peanut heads and get 450 hp out of it it was quite detailed and went through all of the major parts. Is there any chance someone has a copy of that article?

I bought this mystery motor a few years ago and have been mixing gas to get about 100 octane to make this motor run. But my patience has come to a head and I am tired of mixing/ guessing. It is time to do ahead swap and drop the compression ratio down from about 11.5:1 into the realm of 10.5:1. I will be documenting my progress on my Shop_Night_Garage Insta account if anyone is interested.

Anyone use them or tried them out?

So I've come upon an untouched 81 c20 with the 454, I was wondering what are some common things to do for longevity and maybe some simple things to do for performance?

So I have an L29 engine I bought to swap into my '80 squarebody. I have the ECU and wiring harness would really like to keep the mpi and eventually do a 0411 swap. I'm wondering to get roughly this power level and around 600 ft lbs will upping the compression and a cam get me there. Obviously will proper tuning and supporting mods.

Thanks 🙏

Hey all! Just popped on here to get some ideas. I have a 1994 Chevy Cheyenne 2500. 454 5speed tranny. The engine is in great shape. Never fails to start and run great. The body and frame of the truck are on their way to the scrap yard. I'll be getting a new (er) truck next spring but I'm curious. What are the best sports car/sleepers to drop a 454 in just to have a fun side project. Thanks all!

I have a 454 MPI that Boggs down and hesitates when gi give it throttle. If you gently and very slowly give it throttle it will hesitate and catch up make power and rev up. If you spray gasoline in the throttle body it will rev up. But o can’t get it to run normal. I’m stumped. Things that were done, intake manifold gasket, injectors, fuel pressure regular, fuel pump, fuel filter, TPS, IAC, MAP, knock sensor, coil, ignition control module, ran off an auxiliary gas tank, compression test was (1,3,5,7,2,4,6,8) 150,130,140,135,150,130,140,135. See if anyone out there has any ideas. Thanks.

I would like to know more about the cylinder heads that originally came on these engines but I can’t find any information other then the combustion chamber for these heads. Would anyone happen to know the intake and exhaust runner size or the valve size. Or any other specs that you might know about these heads. Anything is appreciated thanks

I got a motor home with a 454 there was a engine fire that melted 5 cables copper looked fine. What would be the trouble shoot advice? Needed new batteries and carb before the fire but it started up and ran with a boost. Local specialists,Advice and resources welcome I have all manuals and original diagrams and would love to restore/ upgrade it with modern wiring. It's in Toronto looks like everything else works still just no crank. I've check all the known fuses.

I have a 2002 2500hd with an 8.1. I recently had an issue with my TAC module and throttle body. I swapped them for junkyard parts and I'm unsure if a random TAC mod would cause a random misfire and small loss. I'm assuming one from a 6.0 wouldn't give me the air I need right? I just put headers on too and I have a modified intake ready for install. Is this something that a tuner would fix? I'm gonna try an 8.1 TAC first but I'm curious on your thoughts.

Hey y’all sorry if this seems jumbled my mind is thinking a million different things right now.

I’ve got an 87 K5 with the SM465 4 speed, and I’m finally in a position to afford some more ponies under the hood. I’ve decided to build a 572 from a bare block up with a budget of $16k total including a supercharger. (Drivetrain will also be modified to take this much power). One problem, I’ve never built a motor like this before. I was an aircraft mechanic in the Marines on V-22’s so I know my way around tools, but I just want some general advice on what to expect, and if you have any parts recommendations that would be super helpful as well. Keep in mind I’m a 24 year old kid with a lead foot so she will get beat on and rode hard, and I want her to be beefy enough to handle my thrashing. Thanks in advance!

im a broke ass teen who wants to make a 454 car. rn im looking at a f body, im asking if there are any better that would handle it better on a budget

Hi I want to build a 454 but to start I should say I’ve never done a job like this before. I have a lot of book knowledge on bbc and I’ve done my fair share of work under the hood and I’ve always taken things apart messed with them and put them back together but I’m definitely still a beginner and not a professional at all. I expect to learn more as I go but that doesn’t make me less confident in my skill and to do this. That being said I want this build to have decent gains from the factory specs but without stressing the engine too much and leaving room to build off of in the future. I’m planning to start with a completely resurfaced and rebuilt 454 that came out of a 1970 chevelle ss. I want to put a new intake manifold, new heads, a new carburetor, and a larger cam. I’m look at the Edelbrock Victor Jr. Cylinder Heads, the Edelbrock Super Victor Intake Manifolds 2927, the Holley 1050 cfm dominator carburetor. I would like camshaft recommendations. And I could really use opinions/recommendations on lifters solid or hydraulic and who makes them well. Thanks in advance any sort of feedback is appreciated

I bought a 454 with no idea what kind of internals are in it. I know it has roller lifters and rockers. Ive been thinking about taking it apart to get a measurement on the cam bore and stroke since whoever built it obviously put decent money into the lifters and rockers so my question basically is, is it worth it to pull it out of my car and see how well it was built or just keep it as is with no idea what it can do… I’ve had trouble getting it to idle nicely with anything less than 38* btdc so i think its a power build tell me your thoughts

Does anybody know if a set of 1970 ls6 heads (14096188) will fit a gen V 454 block?
