I'm at a fork in the road . I need to choose between my 410 cubic inch SB2.2 or my 522 big block Chevy .
Car weighs 2800 w/driver. T400 . 315 radials. 4 link .strut front end . Grudge racing. No rules to go by . Cant decide.
Big block has dart 320 heads solid roller cam keith black aluminum block .
SB2 is 4.155 bore. 3 .875 stroke . Dovovan slum block.
I know the big block will make more power but I'm afraid the 320 heads will restrict the motor , sb 2 is limited in power because of the 2 center exhaust valves . Sb 2 is lighter . Should make 1200/1300 from sb2. 1600 BBC. Sb is 200 lbs lighter . Any thoughts ????
I like the looks of the sb2 and the "cool factor" but can build milder BBC and make more power. Worried about 320 heads. Being small.
any thoughts and advise would be greatly appreciated ...thank you
