So by bumping the compession to 10.1, stroking it to a 331/347 porting out the heads and intake, and a 550" cam I wouldnt add another 100 horse or so mabye? I would think the 347 would give me about 40 hp, 10.1 compression 10, porting 20, cam 20 etc.

I wish it worked that way...but it doesn't. But hey, if you think it is that easy then go for it. Go ahead and spend your money.
Ask your self this...Do you honestly think that a pair off Gt-40x heads are sufficient for a built 347?????
Having more compression, bigger cam and porting doesn't give you more horsepower unless it all works together as a package.
As goes for somebody telling you how much horsepower you should have....the KEY word is "Should". Dyno your car and check. You might find that your off tune and fix it, then be happy with your new found power.
P.S
In my opinion you MIGHT make another 40-50 total horsepower because you did all of those up up-grades as a whole...remember it's a package deal.
