Heavy Duty

What is the difference between a heavy duty 427, and a racing 427?
I have a heavy duty Chevy 427, and I just wondered what the difference is between the heavy one (like those found in the commercial trucks) and racing ones. I know the heavy one has higher torque at lower rpm, but why? Also, would it be worth it to put it in a "rat rod"? Any insight into this would be helpful. Please only answer if you have good constructive things to say. Please don't waste my time, as well as the time of others. Thanks for looking.

The heavy duty ( truck block ) ones have a higher block deck height ( where the head bolts too ) and this allows them to use a longer connecting rod to get an increase in torque.
