All I can find are 3.55s.
Does anyone make a 3.08 (+/-) set?
Even if you could find a set of 3.08’s, I’m not sure you would want them. On paper, it sounds good. If a 3.55 will give you 60-65 MPH a 3.08 should give you 70-75 right.
A 216 does not make enough HP to drive a set of 3.08’s efficiently. Changing to a higher gear ratio is at a cost of low speed power. Taking off you would have to slip the clutch so much it would burn out early. You wouldn’t be able to haul anything more that a cooler full of beer, nor climb any hill. Starting on a hill would be a real challenge.
A set of 3.55’s are ideal for the 215. They will give you 60-65 MPH, without sacrificing too much low end power, thus the reason that is all you find.
Our trucks were built for the roads and highways that were around in the early fifty’s. You didn’t see 70 MPH speed limits. They handle and stop great at those intended lower speeds. If you want to go 70-75 you will have to update at a minimum your braking system and ideally suspension systems for better handling..
