Re: difference in au ef blocks

Probably, why would you do this though, unless you are getting the parts cheap

Re: difference in au ef blocks

Ahh V8 they are all the same.Infact the last engine made in U.S was way back..It is the induction side that got heaps better..
Imo anything over 230-240fwkw is getting beyond a street driven engine.. Another 50-70kw for a 347 stroker.. But other than that forced induction is realy the best bang for buck believe me...No need to rev for power esp with turbo's they turn them into torque monsters...

XRQTOR - It will cost heaps to put AU 220kw stuff on your car, more than it would to buy all aftermarket stuff. If you want 450-500 bhp, you are right on the power limit for the block, so you will need an SVO block, 500hp from a 302 will be a pig to drive slowly.

You would be better off getting a supercharger, turbo or Nitrous, a lot cheaper.

500hp from an NA 302 will probably cost around $15 grand
