318 LA torque?

that 256 degree Voodoo or
Mike Jones H440D64307 256° .461″ w 1.5 .491 w 1.6
Howard and Bullet may also have a cam in this class (well Crower ask our frequent crower poster) and Engle also)
but I think Jones is fatter where it counts it has half again as mutch duration at .275 lobe lift than the DC 260!
These would be Max for a torque pull where you do not want to get on the bigger is better but loose more and more low end treadmill (gears etc)
I still think a 5.9 magnum swap is the way to go
