Another, Damn it, horsepower guess ??

I’m looking at a stroker 408 kit with a beastly comp cam.
Set up:
10 to 1 cr to use 93 octane yes, I know will lose hp
Cam, custom ground 312/597 322/ 588 @.050 solid roller, roller rockers
All forged
M1 or similar intake
850 tweaked thermoquad
MP distributor
MSD 7al2 ignition
150 shot of gas
Most importantly trick flow heads
What I really want to know is the estimated sweet spot/pull hard range??
That is not a pump gas cam IMO. Kim
