1968 327, 3 speed C-10. What is the factory gear ratio of the rear end? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

My 1968 Chevy C-10 was an original 327 and 3 speed truck. I am unsure of the rear end's gear ratio. Anyone have an idea of what this may have been?

My truck had a 307/3ott. It has 373s when I got it (probably original).

3:73s are what I suspected... Thanks for replying. You know, you and I have nearly the same pickup. Mine was that same factory blue and white with painted bumpers. I sprayed a slightly brighter blue, PPG Big League Blue, on mine when I repainted it. great look'n truck you have there!

Most sb v 8s come with 307/308 373 with most 6cyl standard equip in 1/2 2wd but not always.Sweet truck!
