Hey guys, just purchased a 3/4 ton V20 Silverado w/ th400. In talking with the PO, he said the original owner put 3.18 gears in the truck for better mpg?

Anyways, I purchased this 3/4 ton with the idea of towing and hauling. Now I am debating between 4.10 gears and 4.56??? It currently has 265x70x16.5 tires. Probably won't ever go bigger than 33's.

It will likely see a lot of driving at the 65-70 range.

Give me your experiences and opinions!!

Thanks,
Greg
