You are building a "Hot Rod"? Wonder why the drag racers never used the 305? Wonder why they never put a blower on one? Hmmmmm. I wonder if it's because they are so heavy? Or if they won't rev. If they were not built to rev? If they would "blow up" with a blower? I just wonder. Maybe they are good for just hauling like all the ads say. Don't know. Good questions though. Trying to completely redesign a motor is possibly a huge waste of time and money. If a person wants a hot rod motor, they are already talking Chevy. So why stay with original if it's no longer an original 305? Are you building a Chevy inside a GMC? That won't work. There will be no "HOT" in your hot rod. A Chevy 350 with minor upgrades will blow your tailgate off. You are talking more torque. Torque without revs will not produce horsepower....as in: hot rod horsepower.
