Re: Help me build my 454, step by step
Jason, call Dave at the Cylinder Head Shop 331-1110, tell him I referred you. He's done all my machine work and knows big blocks as well as anybody, if not better than most. His shop is on 620, near Anderson Mill.

Re: Help me build my 454, step by step
you'll be ok with the cast crank up to 500 or so hp, if you are thinking about a blower down the road find a good used oem forged steel crank. have the rods resized with arp rod bolts, have the rods set up with floating pins, have the block aligh honed so you get the right bearing crush, have the block decked and squared, balance the roating assm, if you on a budget get some eom large oval port heads and buy and intake from summit, 850 dbl pumper you should be able to locate one here on the boar, there are probablyt some oso members with a set of the heads here too. oh btw, kb hypereutectic pistons are still cast crap, marine engines see a lot of detination so go with trw/speed pro flat top forged pistons. most imprtantly find a good hi po machine shop with bhj fixtures to do you work!!!

Re: Help me build my 454, step by step
Whats the highest compression i can run with 93 octane and iron heads? Looking at pistons now.

Re: Help me build my 454, step by step
I would build based on 89 octane. No more then 9 to 1.

You really need to consider all of the parts as a "system". Choose gearing for the RPM you want to have for the type of driving you'll do - then cam to run well at that RPM - then compression to match the cam - heads to flow the right amount of air at that RPM and lift - intake to flow at that RPM - and so on.
Dave can help you with all of that. |

Re: Help me build my 454, step by step
Trust me, I know nothing about building engines, but I saw a good article in this months Hot Boat about 454/502 rebuilds complete with cam, head and manifold recommendations. Might be worth taking a look

The heads i have suck, and need recommendations on that. So where do we start? Im taking the block in to be bored. do i need anything else done? are the rods good? what should i start thinking about as far as pistons and a kit go? The goal here is to have a streetable car that is fast. i do have a budget, but at the same time want to build a decent engine. no top of the line, but no junk either. i would like to see 500hp out of it. Please be patient with me as i will be asking a ton of questions, ive never done the entire thing before and am looking forward to it. Ill post pics and progress as we go along. Thanks to all in advance Jason Just kidding Take your time and listen to everybody's advice.Good machine work is a must,The engine how to books will give ya a better understanding,theres a bunch out there.The how to blueprint is also a good one. Do a search on the board theres some good threads on here on build ups.. Rob :drink: |
