Ok , heres the deal with your current cam. Its a...

What exhaust will you be running? The 741 cam will not be too big. For a 6k rpm combo, it will actually be a bit small for a 496ci. Id also lean towards a single plane intake on a combo like this.

I agree. Ssm gen 3 are great on forced induction due to their sheer size. NA, they just dont have the runner length. Regular stainless marine manifolds, probably give up 40hp or better on a 650hp NA...

Its really not a matter of how much HP a particular exhaust setup can "support". You can make 800hp thru a set of gils with enough boost in a forced induction build.
