I'm only mentioning engine size because of the extra weight of a big block. I'm pretty sure that this was a factory A/C equipped car, though. Doesn't have it now. How close a trade off would that be? Should I still get heavier t bars for handling? His biggest complaint is fishtailing. Was thinking about moving springs inboard to fit wider tires, but I'm thinking that this kit will give me enough loss of my weekend(s) for now.
