Re: Gear Ratio
Is the shfter up in the middle of the transmisison hump or is it back at the seat? Guys always post those casting numbers and they don't mean a freaking thing when trying to decode a transmission but if it has a shift tower in the middle of the hump it is an SM 420 or SM 465. If it is smaller, slimmer and longer and has shift rods on the side and the floor shift fastens to the tail shaft it is a Muncie M 20, 21 or 22 or most likley A Saginaw both being out of cars. They won't pull many stumps but unlike the 7 something granny gear have a 2 or 3 something low gear. 15 mph is nothing with one of those as it is about the same gears as a 3 speed column shift.
