How much power will it make?

560hp 550tq. If you were planning on running the efi from the beginning, I would have widened the LSA to at least 112* and maybe 114*

I have used this cam before and totally disagree with the statements that the heads are to big(not) and the stroke is to short(not) and the compression is to low(not). It will run real strong, have a great BBM in your face sound. These Voodoo cams kick A$$ and you will have a very good running 440.

I used this very same cam in a SBM 416 with 9.2 to 1 and it made 517hp 510tq the 440 will make more power than that.
