Re: 4bt cummins swap

I would say my 4bt (pump is turned up and different turbo) is somewhere in between a hot SBC and a mild BBC. There is a big difference tho, until you drive a diesel you cant really understand what I mean. Even tho my engine probably puts out 400-420 ft/lb, but at 1600-1800 rpm. The HP is very low, so it doesn't feel like driving a BBC until you hook a trailer to it.... IDK if Im making sense.
