Well my original idea, (being a big block fanatic) was to muscle a 455 Olds or 500 Cad into the engine hole, but when my son and i were talking about what paint scheem he'd like, he brought up the fact that he wanted a little rumble from the exhaust and not the low rider, (pea shooter), sound and i said you have have to worry about that with a big block! Well then he through a curve ball on me and said he didnt want a big block, he wanted a six, (like our buddy "Rock shop daves"), with triple 2's and a nice sound. So my question is.... should i get back the Chevy six and drop it in, or should i rebuild the six thats there now. I actually think the original is a good engine , and just needs a little once over and it will run. I realize the trannys are junk but i'd adapt a gm auto to it, but engine power and afficantcy wise how did they run. I'v got the Super Six. Thanks.
