Ordered a gear vendor, help with deciding gears

The ratio is .78 to 1 (see Final Drive Ratios). This equates to 28.6% faster vehicle speed at the same rpm or take your existing rear gear multiplied by .78 (ie 4.10 X .78 = 3.20). In this example a vehicle with a 4.10 behaves just like it had 3.20s when the overdrive is engaged.
Other examples would be that 3.55 becomes 2.77, 3.23 becomes 2.52. With the .78 to 1 ratio you’re good with any torque converter you choose for high performance street/strip use.

while not as good of a ratio as most of the factory OD transmissions it does do quite a bit.

as far as fit goes the guy i know with the challenger didn't have to modify the floor at all.. the guy with the 73 dart only had to put a little dent in the floor for clearance. not cutting on either car which is huge for many..

i can say most of the fast drag week cars were running gear vendor units. they must hold a good amount of power thats for sure.
