local guy i found is selling #48 heads for $450 and #13 heads for $250, both complete. unless the info is wrong they're both 72cc and same valve sizes, so which is the better choice and whats the difference between them that could rationalize the price difference. My 400 is in the shop 500557 code and is bored .30 over with flat top forged pistons Sealed Power. I'm trying to make 400-425HP street, stop-light car (since that is the limit with the #557 block according to Jim Hand's book) without edelbrock heads
so far i'm set on this cam if it helps
Voodoo Hyd Cam Kit - Pontiac V8 262/268 - Lunati Power
I have my 6X-8 heads still and asked the guy if he has an 6X-4 heads
I understand that i should keep below 9.5cr or so.
