1967 Shelby GT350/500 / Add overdrive to C6
« on: October 15, 2023, 12:38:43 PM »
I'm considering putting a Gear Vendors overdrive on my 67 GT500 C6 automatic. The stock rear is a 3:50 and while that is great for stop light races, it keeps my engine screaming at today's highway speeds. I am still using 15" tires with the 70 profile so that is still a stock setup. Travelling 400 miles on open interstate with even the 18 wheelers rolling at 80 puts me truning well into the mid 3000's I'd like to add the extra gear just to make those segments of travel more comfortable. Anyone done this? If so, are you happy with it? Any information welcome. Oh, yes, I will save and store any removed parts.
