That is pretty much the standard ratio for these trucks from 55 to the late 60's. There was some variations & after 67 there were more available ratios. You are pushing a 235 pretty good at that rate but a good one will do it. Years ago Back when I worked for a truck line we had a 58 for a service truck. I drove it 200 miles on the Kansas Turnpike without hardly ever letting up on the gas. It would go 75 up hill & 80 downhill. It still ran good a long time after that.


They say money can't buy happiness. It can buy old Chevy trucks though. Same thing.
