Cheaper than dirt 318 build

The comp "256" cam only gives up 10 max HP to the "262" grind, but has a MUCH broader (and therefore, usable) torque curve.

...but you lose the roller benefits of efficiency and reduced wear.
or just get a roller with similar specs, I bought a comp roller 210/220 .500 112 with a 1.6 rocker similar to the 256, there another 212/218 114 the one richard holdener got 350 hp out of a 5.9l magnum.
