For all those curious:
In stock trim, both Mangustas (302W) and
Panteras (351C and 302W for last gen) put
out (with a few exceptions) 300-350 HP and
325-330 lbs/ft torque.

Various Pantera owners have had their ZFs
worked by RBT and Pantera Performance, and have
engines pushing well over 400 lbs/ft, some approaching
500+. I would say longevity at the 500+ level
is an issue, but these guys have bored their
351Cs to 377+, or, in the case of Hall Pantera
and others, popped a 460 in and reaching well
over 500 - Hall has one approaching 600!
