I have a columbia behind my 59 ab, single carb, merc crank and cam, not a fire breathing
monster, and I love it. 4.11 gear set, mine is manually shifted, you get 6 gears now, and I use em. They are expensive, especially if you want all the correct controls for your year.
I have none of that, just the rear end and two shifters in the car...34 3w.
