All right as some of you read before I got screwed out of my c1 I was buying to put into my 91 ls, I've got no choice right now but to swap in a b1, unless another c1 or b17 appears at my wrecker within the week. Now my question is i've read a few other forums about guys swapping in a b1 and there talking about using the a1 water pump and crank pulley ect but i don't understand why they need to do this, I know you have to switch the b1 from hydraulic to cable by using the a1 distributor and the throttle body and ect. Is there anything else i'll need to either swap out or change to make this swap work smoothly ?
