what rear end do i need??

[johnunger1001]

I have a 1982 C10 and just had a 350 built up for it. It has a 3000 stall. Right now it has a single track rear end with 268 gears. at 80mph it is turning 2500rpms. Thats great but has no power. What rearend setup do I need?

Depends on how much highway you drive, or if the truck is just mainly a weekend cruiser. 3.73s would be a safe choice, depending on tire size, 4.11s if you want more get-up and go and not so much highway-friendly rpms.
