I run a 2400 stall convertor on my 84 GMC with a 770 R4 tranny, 3.73 gears, and a set of 27" tall tires on the truck. I have a stroked 383 motor in front of the tranny and with my setup the RPMs on the highway is at 2500 at 70 MPH and sllightly above at 80 MPH. When I am in the city, I shift down to DRIVE, so that I would not get into the OD and drop RPMs below the 2400. I have installed heavier duty tranny coolers ot assist in theremoval of heat generated by the slippage of the Torque convertor.

I did the 2400 stall to allow for the cam that I have in the 383 and let me drive in town easier.
