I guess rather than saying they're never going to be quick I should have said "it takes a ton more power because you're working against a tall tire ratio and a heavy truck to begin with".

I would say it is underrated. My 383 stroker is putting out 450hp/470lbft. We have estimated it at around 500hp/540 torque with the new cam and heads i am going to put on. That has to wait till this winter though for when i tear the whole truck down and do a full restoration.
