Rear Gear Ratio Help...? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**67 cst swb** · 01-28-2006, 02:18 PM

So, what are the most common possibilties for a rear gear ratio on this vehicle? (It's 30 miles away in my salvage pile)
It's a 1967 2WD factory 283/2bbl w/ 4 speed (granny first gear)...

are the most common ratios 3.08 and 3.73? Or something else?
And which one is most likely to be what I have?

Thanks in advance...

If not mistaken, a 3.07 should be standard with your engine combo.

Dang-it...
I was hoping you'd say 3.73's... Aw well... I have to check all my rearends I have, in search of a 3.73's... Wish me luck...
Thanks...
