yea someting torqi about the I6's.. cummins is a true work horse. But hell just the I6 in general normally turn out to be pretty reliable motors atleast they used to be i don't know baout theones out these days. But the old ford and chevy 6's and jeep 4.0 good motors. My grandfather had a 70 f100 with a 6 and 3 on the tree drove it for 29 years never had to replace the motor. BMW makes a bad ass 6 as well, M3's are fun cars to drive, not really a whole lot of power mine stock dyno'd around 220 but the gears make the best of it.
