ok I know nothing about the tranny in a B series motor. But I had an idea and wnt to know if its even possible. Is it possible to remove the first gear, slide 2-5 down making them 1-4 now, and adding the LS 5th?? Basically can you put a second gear where first would be?
If this is possible, you could slap this tranny on your turbo B engine, and have a highway rocket. It would suck at a stop light, but once you get going, you could go very fast. It would be a poor mans high speed tranny.
