ill say 590ish hp and high 10's in the 1/4

10.80's if you are in about a 3300 lb car/driver - Heads are too big !! Your going to make good power up top.

Those RHS 230's are usually 235-237cc before clean up.

what size head do you guys think would be better? The guy helping me build it says they will be perfect...and his 82 camaro with basically the same setup runs 6.30's 1/8 on a 125 shot

 

[lilbowtie]

That sound about right. If my quess is right you should have 6.80's 1/8 and a 125 shot should net 6.30's. How hard do you plan on spinning the motor?? what size are your tires?? how heavy??
