Alright guys so when it comes to transmissions and rear ends I am completely clueless. I have my built 347 going into my stock 72 comet, came with a 302 and a 3 speed. Now this car is going to have to go on some long cruises down the highway to get to car shows, but its also gonna have to stand its own at the drag strip. I wanna keep the rpms down on the highway but still have some get up and go. If you all can throw me some options with keeping in mind I wanna do the least amount of cutting welding and custom work possible. Im not throwing out the idea of a manual trans either. Any help is appreciated.
