For a drag race it really doesn't matter, but lake running the diamond drive does hurt top speed a little. Not as much as internet bros make it sound but there is a difference in top speeds.
I grew up on the 90's so that's the old sleds that I'm interested in as far as having an old vintage type sled. I'm looking to get into a nice Jag Z when I find the right one. A Jag special would be cool because it was first year but I like the black tunnel that was on the Z.
