A stock truck on a 4 wheel dyno jet usually makes better 135-145hp around 185ft/lbs so you're seeing about a
177/135 = 31% increase in hp
246/185 = 33% increase in torque
Approx crank power 212*.31% = 278hp
Approx crank torque 275*33% = 366ft/lbs
Watched the video on doing the head work and near the end they talked about putting a garden hose into the top hose of radiator and flushing out the system. Figured I would go ahead and do this now, and avoid some of the mess later. Only thing I did not think about was this artic front coming. So I have water now instead of antifreeze in the engine.
So, it was time for the two rigs to meet...
Also, I went to harbor freight and got more extensions 3/8 and a digital torque wrench adapter that the reviews on have been very high on.
