With a overdrive and lock up transmission I would gear up a ratio. It also depends on your engine, especially the cam, and rear tire size. @AJ/FormS, can you help with the combination?
I guess I need to add a bit more info! It ‘s my conversion wagon. Engine is a 66 273 Formula S built to pretty much stock specs. Cam is from Racer Brown nothing exotic. Trans will be the A500 with OD and LU with a stock style converter spiced up just a bit by Dynamic Converters. Rear end will be a LBP 8.75 that currently has a 742 case 3.23 Sure Grip in it that should have worked nicely with the 65 833 that WAS going in. Rear end is sitting on a homemade stand is ready to be installed so right now gear swaps would be easy if needed. Tires are gonna be 14 inchers since that’s the size wheels I have - probably no bigger than 215-60’s or 70’s
