.....that's my concern too Paul. That's why our Duster has a 727. With the completion of our W5 mill when my dad was wheeling the car, the last thing I wanted was for him to have to babysit a transmission.... so 727 it was. Kind of the same reason we chit canned the 8.75 for the D60. Just one more thing on the "set it.... and forget it" list.

The 904 we have was behind our 10.9/low 11 iron head 360. It was built by Chuck Lofgren and other than the Griner trans brake, nothing real extravagant. I think it would be interesting behind our current W8 mill, although an expensive test as I'd need a converter, driveshaft, and imho... a good input shaft. Maybe someday...
