440 what am I missing here?

A decent shelf grind based on Andy's criteria, but not quite as much .050 as the .528/284 Mopar solid. Being a single pattern camshaft, it probably would work better with headers.

If you stay with exhaust manifolds, then I really like this grind, but availability may be somewhat sketchy now. Crane lists it as being best with 2000 rpm stall. If it were me, I would risk leaving some power on the table and run with this because it should play very well with the FI Tech.

One of Comp's XE 274 grinds is also very good, but would be even better if ground from a 110 LSA to a 112-114 (depends on what Comp says is best for the FI). It would easily make the most power of all three of these cams.
