Horsepower is the rate (how fast) your engine is making torque.

Jared has hit the nail squarely on the head. Damm, why didn't I think of that?

hp vs. tq

600 lb. ft. of torque at 2626 rpm = 300 horse power.

300 lb. ft. of torque at 5252 rpm = 300 horse power.



Which way would you rather have your 300 horse power?

& on our beasts, unscientifically, from plate mfgs & from the various dyno posts, HP x (2. 1 to 2. 6) ~= torque.



For example, for the properly valved, 12v that is, one of TST's plates is rated at 230/605, multiplier = 2. 6. One version of the stock 12v is 215/460, multiplier = 2. 1. Lots of other examples ...
