I run 33's on both of my 2.6 Raiders. I can cruise at 80 no problem. But I have an extra 100 hp.
They will fit without a lift, But I would put a two inch body lift on it. The weber carb might help. But you will probably not see 80 or even fifth gear on a hill.

Well on my way to becoming that eccentric old man in every town.(crazy as a s#@thouse rat) With a yard full of desireable old vehicles that tells you, Sorry they're not for sale..... Someday I'm going to fix them.
