This is a useful conversation. i have been thinking for some time about the drivetrain that will go into my '52 Chevy two-door behind a 320-cid GMC now abuilding. The time will soon come when i shall have to acquire the rest of the pieces. i intend this machine as a "hot rod" of the 1950s; it is, clearly, a "toy," but i want to be able to drive it wherever it needs to go. i don't own a trailer and don't want one. i want it to accelerate as quickly as it can, but i also want a good top end. Why build it, if i can't drive it . . . fast?
My plan is a "close-ratio" three-speed (2.2 low) with overdrive and a 4.56 differential. i have 235/70x15 tires on the car now, and will use something about that size. A '52 Chevy with GMC is not a lightweight, which is another factor that encourages lower (high numerical) gearing for the street. The overdrive makes it possible to enjoy the power the engine produces on the street and on the road. Or so i think. i intend to find out.
God's Peace to you.
