I have built and am installing a 455 ci olds engine bored 30 over with 9.5.1 compression and a W31 cam in my 57 oldsmobile. I plan on installing a TH400 B&M tranny. Question, What rpm stall convertor should I use for street use. Next question, I don't like the two piece drive line. I don't think it will hold up.Has anyone converted to a single drive line? If so how did it work out and what did you use?


Thanks
