Thanks for the input y'all.
Looks like I am going to roll with what I have for now and spec a cam accordingly.
I will definitely look into building a big low deck stroker in the future, but since I already have an assembled short block and heads, I'm going to reevaluate my goals and build accordingly.
A 496 stroker with good modern heads and technology seems to be in my future, but I'll see what I can get away with now and see what numbers it puts down.
