I put a 4.10 third member in my 1951 1 Ton and I can cruise at 60 mph. I have fairly tall 16" tires (spec'd at 652 revs per mile) and that gives me just under 2700 rpm at 60 mph. I have the original 216 in the truck. I don't haul any loads.


1951 GMC 1 Ton Flatbed -- It is finally on the road and what a great time I have driving it!
