I am building another turbo car and trying to decide what rear to put under it. I have a 340 demon with a turbo and 8 3/4 with 3.23 gears i drive alot and i think it would be even quicker with 2.91 . this other car will be indy headed 440 with twin turbos so the 8 3/4 is out of the question. the only dana 60 gears i see are 3.54 gears and thats too low. I dont like the idea of running a 9 inch unless i have no other options. I want something around 3.08 or 3.23. what would be my best option to keep it all mopar?
