I've been seriously contemplating a 460 swap and doing much research on it but I stumbled across quite a few articles on 302 buildups and I was surprised at how easy it is to hit 500 hp/ 400 ftlbs on a stock cammed 302. Since the 460 is only about 500 hp/500-550ftlbs in the combos I also stumbled across, I'm seriously thinking keeping the 5.0 a 5.0. I have reached the conclusion that aluminum AFR heads and 1.7 roller rockers is the way to go to reach that mark.

Basically, this was the one article that inspired me:

So I looked at AFR and the 165 cc and the 205 and the 225 cc heads are all comparable in price (within a few hundred). What would I lose by simply bolting up a set of 225 cc heads to the car (to leave room for expansion: the flow on the 225's is astounding!)? What about 300+ cc heads (I saw them in their catalog)? Would I lose compression? Would the 225 flow as much as the 165 but not reach it's potential? I'm fine with that....like I said, room for expansion.

Thanks guys!

Keep up the good fight,

Pete
