440 what am I missing here?

A few thoughts.......

Needs WAY more stall than anything rated at 2000.
A tight 9.5” would be more like it(3700-4000).

Initial timing is way low for a cam like that.
Should be up around 20-24.

Not the answer you’re looking for...... but........in reality....... about 10-12* less cam duration on a 112lsa would work way better........ if you care how it drives more than you care about “the big number”.
The shorter cam would be better with a milder converter, along with it being easier for the EFI to deal with.

Love the truck though:thumbsup:
