Hey all - Anyone doing LT swaps yet? I love the LS/T56 in my 68. Since the engine and trans in my new 79Z28 are not original I was thinking LS3/6L80E but have been doing some research into LT1/8L90E. I know that in either case the trans might be a bit of a stretch from a ground clearance stand point but will use a T56 Magnum or 4LXX as a fall back. I plan to keep the car stock ride height so not sure how much of a concern these auto trans' will be. I have read people with lowered cars have ground clearance issues but I don't plan to lower. On to the LT vs LS question..... For anyone that has done the LT swap so far what are the significant differences that may pose roadblocks compared to the LS swap.
