so the trans bolt pattern is the same.
for a small block GM 350 and the 6.2/6.5L diesels

3,500 rpms is quite high for a 4BD or 4BT engine

2,800ish rpms is commonly red line for these engines.
so re-gearing to 3.55/3.08 range would be needed to turn mpg friendly rpms at 60 mph

i know the 4BD and 4BT model is around 750lbs + trans how does that compare to the 6.2L 6.5L?
