Beefed up My six, need more power to the Rear

OK,first the basics, torque is force applied,and power is how much
work is done per unit of time.Horsepower is just a calculated number based on that
fact so different sources of motivation can be compared.
I put this in another post, but I'll repeat it here,THERE IS NO TORQUE
VS HORSEPOWER !!! They are one and the same,because Hp is simply calculated from
the available torque at a given speed,that includes the wheels. The engines hp doesn't
change,so the terminal velocity will end up close to the same for a given setup ie Qtr.
mile vs 8th mile vs top end maximum.Optimized drivetrain gets you there the quickest.
The right torque converter can be the difference between a 102-103
mph in the qtr., and 107-108 mph in the qtr. ,you wanna tell me that isn't more hp at
the wheels? I've seen it/done it.Same car/cam/gears/carb/exh/tires you name it,the only
change was the torque converter.
The problem is terminology,low RPM efficiency has been tagged"torque"
and high RPM efficiency has been tagged "power",but they go hand in hand.A great eng.
has a broad torque curve efficient over a greater range,a poor one has a very narrow 1.
I'll confess I haven't looked up the cam the OP has to see what the
RPM range is supposed to be,but stalling it even 400 rpm under where it's efficiency
begins will totally kill the bottom end "feel" and times.
