I have a 1951 Chevrolet 1/2 ton Pickup. I have a 350 with a Muncie (M-21) 4-speed. And the rear end is out of a 1970 GMC, with a 6-bolt wheel pattern. I think the rear end gearing is 3.73's.
When I'm driving 60-MPH, my tach says 3400 RPM. (My speedo has been recalibrated to spec's) What I'm trying to find out is what ring & pinion gearing would work best if I was to change it, using the same rear end?
And if so...what good supplier would have them? And how hard is it to change?
I'd like to lower the RPM's in 4th-gear, going 60-MPH. Could somebody please help me with information that I need on this subject?
Thankyou...Jeff
