currently my engine is a pretty stock 289 with a c4 trans. I think my rearend is a 3.00:1, but eventually I am going to put something like a 302 or 351w and a tremec TKO 5spd. Also, I wanted to get a new rearend from Currie enterprises. So, my question is, can I get the rearend before I get the transmition? What gears ratio would/should I get, or would anyone recommend? I am sure there are unlimited set-ups that i could get so any suggestions from the pros are welcome. Or should my next step be to get the TKO from darkhorse performance and then get the rearend. My car is on jackstands (and probably will be for a while) and I am holding off on putting on the new suspension until I get the rearend.
