You can go to the engine manufactuer and get the specs on those motors. My old school 3406B is 425hp/ 1450 torque.

4 and a quarter B model? I had one in a 94 Pete I used to drive, would do triple digits. Don't underestimate those early CATs. But since your just stirrin the pot I figured I would bite and give my $.02.

You got that right, mine is a 2100 rpm motor with the heavy duty valve springs etc.
