Quote: Griner makes a fully manual valvebody for the 500/518s. You actually make the 3rd to OD shift with the shifter.
Wow, I didn't know that! Do they advertise this anywhere?
Anyway, to answer part of the original question...I use a 518/46RH in my Dakota. Not the original one now. I've had a non-lockup version for the past 5 years. Automatic valve body. I turn off the OD at the track.
Doesn't seem to do too bad for a small engine in a fairly heavy truck. See sig for specs. A 727 "should" be a little quicker but haven't tried one yet because of my gears and highway driving.
