Alright, I know I've been wishy-washy recently but a lot of money is going to be spent so I want to make sure I get this right. So I'm going to get an lt1 motor (5th gen....Gen V because that matters I guess) and throw it into my 1975 with this kit. I don't imagine I'd run into too many issues.... But here is the part that I've had trouble with... The transmission. So originally I was going to get the 8 speed 8l90e but that probably won't fit and others have claimed that will only work in a corvette.... But I want this ratchet shifter and that won't work anyways. So right now I'm looking at a 700r4, but with that being such and old transmission and it's not using a computer, would that have issues? If so could I use a 4l80e transmission with the shifter I want? What other options are available to me... And what things would I need to buy to make this work? I'm going with a 4l75e, 4l80e had clarence issues and I didn't want to hack up the interior of my car. I verified that I can still use my shifter and not run into any problems.
