I just picked up a really nice Saginaw 4 speed. It has been rebuilt or was not in a vehicle very long. The case is perfectly clean.
It is a wide ratio 3 groove unit, 3.50, 2.48, 1.65, 1.00 ?
I think I'll replace my SM420 with it, it should work well with a 3.07 rearend. The 420 is 7.05, 3.57, 1.70, 1.00
Who has one of these, and what shifter are you using? What should I watch out for? It will bolt right into a 261 bellhousing, right?
