OK, using Chevy's numbers from the owners manual the 216 shows the net torque pretty flat, from a peak of 168 lbs/ft @1100 rpm, to 164 @2000 and 160 @2400. On my 1 ton dually with 18" wheels (32" tire height) and 4.11 gears, 1950rpm=45mph, 2160=50mph and 2375=55mph. The net horse power at those same speeds come in at 62, 68 and 72 respectively.
I think these are very workable numbers. Again, thanks for all the input!
Now I've got to find that pumpkin!
