I have done some searching here and found a ton of information, you people are amazing. I am about to embark on an engine swap in my 280Z V8. Right now it has a Gen 1 350 and an old Chevy Monza 5 speed, both of which are getting tired. I bought the car this way and the drive train was installed without the use of a setback kit. I will be using a stock '95 Z28 350 LT1 engine in this new setup. I have not decided on a transmission yet. I'm torn between a world class T5, which seem to be hard to find, a T56 and an 4L60E automatic. This car is a daily driver, not a racer, and since I live in the city an automatic would be nice although in seems almost sacrilegious to have an automatic in a sports car. Right now I have 2 questions. Whose mounting KIT do you think works best with a LT1? My second question, I read here that the transmission tunnel needs to be modified to fit a 4L60E. Just how much modification are we talking about?
