Richard is right, these transmissions will not take the strain of a modern ohv for very long. Sure, you will hear stories of how they ran them on altereds and diggers of the day, but they didn't get many runs out of them. I used to go through so many Chevy 3 speeds that I carried a spare in the trunk!! After a couple of powershifts 2nd gear would lose a few teeth.

There was a reason people ran the early Ford 3 speeds. We had nothing better, unless you opted for something like a Cad-LaSalle, Packard, or similar heavy duty 3 speed. This back to traditional rod craze has guys buying up early ford boxes and rear axles again, to get the look. If you treat it like granny you will be ok, but a few more smokey burnouts and you will be looking for a replacement.
