Thinking about building a chevy plant in my jet...
Starting w/ a block, what would be a good recipe for 500 ballpark HP? I was thinking of starting w/ either a 454 block, or even a newer dart or merlin 500ci block, and then going from there...I was also thinking of putting a mild 6-71 on top also, or it could be NA...so, if some of you guys have some time, could anyone make a list of what i roughly need? im still learning, SORRY :devil:
thanx,
Reid

You also need to decide from the start weather you are going to build a blown engine or NA engine.
Oh yeh, first things first. What about your budget.
Thats the primary regulator of your HP.
I run a 509ci blown BBC with F.A.S.T. fuel injection, alcohol injection and intercooled producing up to 1400 hp on pump gas/alcohol inj.
To go that far, building it yourself plus machine work you are looking at ruffly 30k with new parts.
A stock BBC 454 four bolt main engine is good up to around 800 hp. After that you need to go to a aftermarket block.
The only suggestion I have at this point is if you're going with a blower, use an 8-71. No use running a 6-71 hard to feed a big block. An 8-71 will provide more flow with less heat build up.
Buy a crate motor. Have it remachined for marine tolerances and put the right cam in it. Probably be a lot cheaper and should make over 500hp no problem.
500 hp is not to hard to achieve,especially with a 500 inch engine,there many combos you could use for that and make more.That would be your best way to spend $$ is get that good aftermarket block and it should last forever.
I will go for that! 500 HP is easy to acheive 454,461,468,Etc.just in stock stroke. But do keep in mind that compression has to stay in perspective about 10.7:1 or less unless you are willing to pay for race fuel $$$$$$!
Go Ford!
I have been contemplating switching my Chevy for a Ford. Maybe we can do a trade on the stuff?
just to cruise! no racing here for sure, and id rather go NA...so a regular 454 block will last up to 800HP? thats perfect! i didnt know that at all...good news.
