I have 3.55 on mine right now and it's too low for me since I'm not doing any more of that drag racing any more. I'm not like 10-20 years ago. I just want a stock one. I also want to change out my under drive pulleys.

thanks

 

I want to say 2.73:1 was stock with 3.08 being an option. Probably find someone local to trade straight up and do a whole rear end swap yourself and not have to pay to set-up the gears.

 

I like 3.08 better. I will post it on craigslist.org. Hopefully I can find someone who wants to swap with me. I live in Atlanta by the way.

Thank you.

the 273/308 is correct.

googe gt registry, they have a list of changes by year as well.
