Im back,,, If you build a blown,stroker small block of 377/391 range you could get 750 plus horse power using a 671 blower /roller cam and 195 heads. your throttle response will be instant. The car will scare the pants off ya.
lets go over the parts list you need/want. you can make 450 hp with out the blower,,,, post or PM the cam specs and what you have and lets shred some tires,,,seriously a blown big bore small block in a car weighing 2000 pounds will break the tires loose at 60 mph just by dipping deep into the throttle.
