Something to consider for those that want to run hot cams, on the street, is that 3.35, T-5, 1st gear trans. With 4.11 or 4.54 gears, it will get you going better, from a stop, w/o stalling and even with a 4.54 rear gear, you have a final drive gear ratio of 3.09 and still have a very hard pulling car, in 2,3,4th.

I have a '48, F3 truck, with with 4.86 rear end and 33" tires. I put a AOD, behind the 302, giving a final drive ratio of 3.353 and that that lowered my 65 mph, RPM from 3200, to 2200 and much better MPG, on the fwy.
