Today was the second time out in the truck. OEM rear end and stock 4 spd trans and 302 engine. I have the rear end to swap out but I may need more than that. Comfortable sounding speed was about 40 but could go to 47 wound out a bit. I anticipate 20% gain with the rear end swap but still that puts me at 48-54 mph. I'm thinking I will need a different trans ultimately to get out on the road to travel. If the T5 is not up to the task, then what do I look for?
