ok so i just installed a t-rex and had it tuned by at futrals. he said that i deffinately need to change my gears now so being that a have a th350 (no overdrive) i dont want to go to high and loose all of my top speed and cruising capability. so im stuck between 3.73's or 4.10's

what would you guys suggest?

 

If you do some decent highway driving, I'd stick with the 3.73's. I have 4.11's in my iroc with a th350, and 70 mph is around 3500 rpm. But, I only use the iroc for the track, and I drive it there and back. If its just city, and track, go with the 4.10's.
