Tom, if you don't mind, let us know the results as far as fuel mileage, power, etc when you get the truck on the road. I had thought about switching to 3.08s or 3.42s when I put the big block in but I love the low to mid range torque the 3.73s provide. After all, I didn't put the 402 in there for fuel mileage...
