4.57 standard gear ratio?
I have a 1970 C20 with a 250 and 4-speed setup. I just read in the original sales brochure that the standard gear ratio is 4.57 in this truck and the 4.10 and 3.54 were optional. Is this correct? I guess it is a good thing I bought the original size 7.50-16 tires to keep the RPMs under the moon.
Wonder why the C20's standard ratio is 4.57 and the C10's standard ratio is 3.73.
