how to hit 400hp on a fox stang

budweiser · Jun 29, 2004

ok what would i need to do to get 400hp out of a fox stang 225hp stock .... i was thinking heads (AFR/TFS), cam, intake (edelbrok performer RPM II) 80mm throttle body.....i was also wondering if that holley engine package for 86-93 EFI that produces 350hp ...... it has heads cam intake roller timing chain pushrods and cylinder head bolts ........then maybe add a 331 or a 347 stroker kit to get that final 50hp... what do u folks think??

400RWHP is going to be hard with a N/A 302. Especailly if you want it to be streetable. It would have to rev high. A SuperCharger alone won't do it, but I have scene the dyno of a stock from throttle body to oil pan pack out almost 400RWHP and almost 500RWTQ. Maby a bottle would get you there. 80MM TB??? Maby a 70-75mm TB with a 80MM MAF.

400hp is definitely achievable...although the "streetability" will be limited. Check out this article:

Probably the AFRs 185cc. i wouldn't run them on a 302 though, might be a little too big unless you have a big cam.

Motor Swap!!!

Here's a good start!!!

Do you want 400 to the flywheel or 400rwhp? 400 flywheel is like 355rwhp assuming 15% drivetrain loss. I think you could get there with a really nice h/c/i setup on a 302 or pretty easily with a 347. Ported trickflows, nice intake and custom cam on a 302 or you could go 347 and probably get away with box stock heads and parts and make the same numbers....

wow, i think i need those afr's.

You guys need to remember that this is totally stripped down on an engine dyno. That motor would put down around 280-290 rwhp in a Mustang through a 5 speed.

i have the tfs kit with a dss 308 and hpe for 280- 315 rwhp. And then eventually put a blower on and that should be 400 with a port job.
