All US cars delivered with a V8 & 722.3 had a 2.47 final, and some euro cars had a 2.24 final.

Do you know if a gas valve body can be modified with diesel parts to have a full time first gear start? Or possibly using the gas springs in the diesel valve body? I'd imagine swapping the entire diesel valve body onto a gas transmission would mess up the shift points. I assume they have weaker springs for those 3000rpm shift points. I could probably do some research on this on my own but I figured I'd ask.
My SLC currently has 2nd gear starts with the 3 speed and I do not like having to manually select first. It ruins one of the few positives about autos IMO. If I'm going to have a torque converter I don't want to have to put thought into gear selection.
