Re: Three speed Saginaw top speed ?

Gear the truck for what youre going to use it for:

If you want a heavy pulling, heavy hauling truck--then stay with a 4.11 gear. If you do mostly town driving and no or little towing then a 3.73 will be perfect.
If you are building a cruiser and wont be towing and want good hiway speed cruising then go with the 3.08 (or even a lower numerical) gear.

As far as "performance" off the line---depending on yur engine, tires, etc, you can launch one of the trucks as well with a 3.08 as you can a 4.11.

Im using a car 4 speed and a 3.08 in mine (when it hits the road again) and I can guarantee that combo will smoke any tire I might run. In my other street machine (the 54 chevy hardtop) Im running a mild 350, a th350 and a 2.56 rear----it weighs as much as a short truck, and it will get it off the line and pulls like crazy in second.

Anyway, just saying,, make life cheap and simple----dont kill your wallet with a 4.11 when a 3.08 might do!!
