I would like a higher gear ratio for my 68, 428 C-6 equipted, Convertable, with 9 inch Detroit Locker, approx a 2:78. Do You have a Ring and Pinion set that will provide something near that? I am currently running a 3:00.

Asked by: Dave 1221
No, unfortunately, we don't have anything at that ratio (or near there) in a 9-inch rear end.

I have a 69 Mach 1 351W-4V. I am currently running the stock 9" with 3.0 gears with an FMX tranny. I would like to install an edelbrock top end kit. My question is, how high can I go on the gears, I was thinking 3.5. Do you sell that?
