I am sure several know this but:
Horsepower is nothing more than a mathematical representation or torque vs. RPM. Horsepower is the measure of work a horse can do. 1 Horsepower = 33,000 foot lbs per minute of work. The formula is (Torque * RPM) / 5252.
Depending on weight and gearing, yes a diesel truck can smoke your A$$ at the track. You give me the right gearing, a 1500rwtq diesel engine, and 2800 lbs with driver and I'll show you. I'll cross the 1/4 in 10 seconds at a blazing 2900 RPM,
I don’t think a 346, with the same weight, same gears, etc, making 502rwhp and 392rwtq is going to keep up with me – it will make a lot of noise because to make that kind of HP with that low of torque, he has to be twisting that motor to 7 grand.
Think about this. My buddy’s ’04 Stang makes 550rwhp and 590 rwtq – yet I manage to stay right beside him on the highway. Why? Looking at his curve, you see torque building as a function of RPM/Boost, whereas my torque curve is flat’ish across the band. My more efficient 461 torque curve is keeping me there – against his massive “peek” torque of 590. And I smile all the way to the bank!

Sounds good to me, I stand corrected
