TH400 + 3.08 Gears; Motor and Tire size? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Putting a TH400 and 3.08 gears in my 69' 1/2T 2wd - deciding between a couple motor options still. From my reading trying to edumacate myself, it sounds like the motor, transmission, gears, and tire size all affect each other?

Given the TH400 and 3.08's - will I sill be able to take good advantage of a high-torque motor like this:

How does tire size affect all this? Do I want smaller or larger tires?
