What Cam is fo me?

I'm not sure. IF you had all the specs of the engine(And head flow abilties would be great) I could run it through a program (Desk Top Dyno) for a compare. It has a good bit more exhaust duration and a little bit more on the intake.

I like the Crane above, but the 114 C-line will not have a choopy idle you desire.
IMO, Horseheads cam is to big, it will lack the low end torque your looking for and I myself would use the 340 replacement cam if it were to be a purple cam, but his cam can move a car!

I think everyone has a good idea on a cam. Mopers is a good choice that'll have a nice thumping idle to it.
