Thread: Newbie on 454 Rebuild

Tweet

okay so i inherited a 454 4 bolt Mark IV it had been sitting in a car port at my grandfathers he wouldn't sell it but he gave it to me and i have never worked on an engine b4 so this is my hands on learning experience. so i was looking for some input on good ideas for what i want to do. i have plans to put it into a 1st Gen camaro 67-69. i want the engine to have maximum visual appeal so i figured ide put a supercharger on it, so now im here to get some good ideas of what i need to get the engine ready to handle that and also put up some good numbers ie.. HP/TQ. i did strip it down to the bare block to have it hot tanked and then magnafluxed pressure tested and all mic'd out to i know what sizes im gonna need as far as pistons, rings, bearings, etc... other than that i do not know much about what kinda parts to look for or what would be the proper super charger to use or elctric or mechanical water pump or fuel pump so if some of you Guru's have any knowledge that could help i mean any at all, it is very much appreciated. thanks.

what kind of supercharger were you thinking??? a procharger with a intercooler and a water/meth injection and a blow through carb from pro-systems running on pump gas will dealer 900hp+ with good thought out parts..i have done procharger engines from mild to over 1700hp on pump gas.. what kind of power are you looking for???

for anyone to help you you need to tells us thats alot hp/tq ?if you are going past 600hp you may want just to start with a dart world. bow tie block 4340 crank .H or I rods better heads what heads do you have? how much money do you want to spend ???? to get THE LOOK

Like Pat say's past 600 hp and you may want to look at the Dart blocks.
I have run them past 750 without problems but the problem with the supercharger is 9 lbs. is good but 12 lbs. is even better.L.O.L

I just rebuild my mark IV 454. I stroked it to a 496 using forged Scat kit which included H-beams and all the bearings. I used probe forged blower pistons, had a custom cam ground (for marine applications) and am running a B&M 177 blower with a demon carb. Should put out a reliable 600-650 hp on pump gas (low compression like 8.5:1 or so). I am just using hand ported 781 heads with 2.19/ 1.88 valves and had the exhaust changed to hard etc. My blower puts out 5 psi so it won't kill my marine engine which will live most of it's life in the high rpms and on the boost the whole time.

We have a spare, fresh 6-71 blower, BBC manifold, pulleys (49T & 51T), Enderle Bug Catcher, EFI spacer & injectors sitting on the shelf in the shop. Just what you need to top off that Gen IV block when you're done.

PM me if you're interested.

Cheers, Mark
