Yeah, he said I'd be looking at 13:5:1 compression. Can't be doing that at all. But everything else in the build is solid. How difficult would it be to just put in some flat top pistons? I mean, I can just change the pistons right?

Blocks if done right are bored to the piston manufaturers recommendations and if done right each bore is set to measurements pistons require. Personally, I wouldn't feel comfortable putting/swapping pistons in your above situation to save a few pennies as it could cost you more in the long run.

barnett468

if you get lucky and the bore is good and you find pistons that fit which is possible it would be a good idea to balance the pistons and the engine.

Just MHO but I don't really think that the OP has enough money to build a 363/370 to 500+RWHP and do it right.
Couple calls to quality race type machine shops and doing the math on parts costs alone will show what I'm talking about........

Dj_Seph

True. 10k might not be quite enough. Already looking at 6k for a motor. And the transmission outlook is looking grim. Hm.

mjr46

6k is stock block build territory 347...heck I got more than 6k in my 347 stock block set up

Dj_Seph

Yeah. Easy 8k full build with what I have right now for this engine. No worry though. I've decided to take the advice of another forum and take this slower so I started by ordering a TKO600 kit from hurst and a 4000cfm double fan setup from AMP performance. Then I'll save and do as you said mjr46 and just get an engine from Fordstrokers.

barnett468

do you have a link to the fan. it is likely much less cfm that that. it must draw around 40 amps to be close top 4000 cfm.

Dj_Seph

Not currently but check out AMP performances web site. Not sure if they added it or not yet.

barnett468

you need to make it easy and post the link to the exact fan where it says 4000 cfm because i looked for it yesterday and did not find it.

here's what i found
