I have quite a dilema on my hands, not sure what engine combo to go with. My goal is to have a low 11 second truck. I have a 454 and a 350. I have talked to two engine builders and they have different opinions. One is to build a 496 with about 650hp. The other shop recommended a 383 with about 550hp. They said the weight of the bb would make it even harder to hook than it already is. I don't want to regret not going with the bb.
Either engine would have aluminum heads and forged internals. Any opinions would be appreciated.
