Inliners International Forums General Discussion Drive Train 700R4 behind 292 ('68 C10)

I have no real interest in hot rodding the truck. I just want a tranny that will have a lower first gear and overdrive for driving around town. The 700R4 seems to fit the bill, and it appears to be plentiful and relatively cheap.

Is the truck application 700R4 different from the car application? What application would more closely match mine with respect to motor and gear ratio?
