What? 'Nother 360 magnum on the dyno?

Great timing. I was just starting to research 400-450 HP 5.9 builds.

Not a lot of info to be had.

x2 on tq curve!!

Does that cam use the factory lifters or do you have to use the comp lifters?

What do you think might be the "next step" to get to 425 or 450 without losing too much torque?
