The 3.70 rear in my 1969 L46 Corvette is quite annoying on the highway. However, the close ratio is a lot of fun at lower speeds. I was originally thinking about swapping in T5 Borg Warner transmission however I understand they are not very strong. Nonetheless, that remains my current plan as I do not intend to throw a ton of horsepowe or torque at it and do not want to spend a fortune on a Mega buck transmission. I would be looking for something used to drop it or rebuild. Any thoughts on this?
