I just put in a 75 280Z tranny in my 70' 240Z. The gear ratio sucks compaired to my 70'. I have a 72' tranny and I really like the ratios, I don't think they are stock. my 70 needs a rebuild bad all the gears make alot of noise especially 1st. My 72' needs work on 3rd ,4th, so I'm going to rebuild it. What I really want to know is are the pick-up tranny ratios very different from a 260 or a 240. I know 1st is 3.54 in the 240 and 3.59 in the 260. Whats 1st in the pick-up. I want to leave the rear end stock. Just looking for a little more umph.
Thanks alot.
