the Cumins in 60CI per cylinder, if it was an 8cyl it would displace 480ci. More cubes per cylinder makes for bigger pistons and longer strokes. Plus it's an inline motor, so 7 main caps, more mains than cylinders makes for a very strong bottom end.
What can I say, I like the inline motors. Plus the cumins that I have driven pulled like farm tractors, than cars.
for RACE purposes there is no argument against 12V cummins. Huge aftermarket, and though it has already been said, inline motors are naturally better at holding together. I love my new PSD but Cummins makes a hell of a motor....or....used to anyway :P

Duramax for drag racing and it is streetable. You also have better fine tuning for launching in any application via EFI Live. I think nolimit diesel performance is in the 10's.
Not to mention, building boost on a dyno, and at the truck pulls is completely different then trying to light a big turbo or even twins at a track. Esp if this motor is going in anything but a truck, it could be a real challenge to stage a cummins in a car.
