    Short Shaft Slip Yoke 727's in Old Airport Tugs?

    No, because what I am after was a very specialized application. Most transmission supply houses no longer stock hard parts for old 3-speed transmissions anymore.

    440 power gains/ aluminum head advantages?

    Not degreeing a cam is a huge mistake a lot of guys make. You can never assume it's going to be even close. If you put a lower cost timing chain in they will stretch and you'll lose 2-3 degrees within a 100 miles. You don't have to pull the heads to degree a cam, but that's the first place I...
