I currently have a 79 z28 Camaro that I have been drag racing a few years, now. It currently has a decent 355 in it right now. I am wanting to slowly build my dream blower motor and drop it in the Z when it is finished. My dream motor since I was young was to have a blower sticking out of the hood. I have decided the type of blower I want but, not the size of motor. I grew up building chevy small blocks with my dad in his Nova. So, should I go with a 383sbc or a 454bbc motor to compliment my blower? What are the pros and cons of both motors? This will be strictly a drag racing motor.
