how much hp gain from just a cam?
Here's our situation for those of you that don't know our combination.
2004 Corvette coupe: all bolt-ons - 1 & 7/8" ARH, no cats X-pipe, B&B Bullets, Yank SS4000, 3.90, Bogarts, Hoosier DOT 295/50/16 drag radials, UD pulley, Vararam, tune, ...
Race weight is around 3300 and NA it's made 372. Best ET is 11.58 @ 115 in good air (not great) with a 1.50 60.
The car also has a wet kit (with NANO) and on a 100 set-up it made 502. We haven't had a chance to sort out the progressive controller yet but once we get some runs I'm comfortable it will go mid-10s.
So here is my situation. I'd like to sneak in the 10s NA and 9s on nitrous (can up it to 150) in good air on a good track. How much HP will a cam add and can I do it with the stock heads and intake? I have a daughter in college so for now I don't want to invest in a $2K+ set of heads and I'd really like to have a 9-second car with the stock 241 heads. If the cam alone doesn't get me there I'll put a FAST (or MSD when the results come in) intake on it but I'm really trying to keep this as simple as possible.
Thoughts?

My thoughts are i would put a ewp on it, a fast or msd, do a little weight reduction, put a set of 1.8 rockers/springs in it and a electric ps pump and pic up 3~ more tenths.
It's runnin pretty good now. Tweak on it a bit more! Hell you can outrun a pile of cammed cars now.

No, to be honest with you I've spent WAY too much time over the past year looking at cam companies and cylinder heads. It's overwhelming. I think I've come to the conclusion that there isn't one magic cam (pardon the pun TSP) and there are several good options out there that will make within a few hp of each other. I'm leaning towards Martin at Tick.

If you changed nothing else but just did the cam I'm not sure that alone would put you in the 10's. To go from a 11.58 to a 10.99 with just 40-50 more hp is going to be very tough if ALL else remains the same

I'm putting a 6-point bar in the car this summer so I'm not interested in running 9s all the time. Just one of those deals where if the weather and track is right. 10s NA would be cool.

Yes, I looked at several cylinder heads and had planned to go the H/C/I route. But I ordered a 6 point bar from Wolfe to install this summer so that was a grand. Also, and far more importantly, our daughter will be heading to college this fall and that is financial priority number #1. A cam change, along with timing chain, oil pump, valve springs, trunion upgrade, etc. is about a grand also. If I can achieve our goal using the stock intake and heads for $1000 vs. $4000+ then I'd rather go that route. Martin thinks we can get there with a SNS Stage 3 Torquemax cam. We do our own work and never plan on spraying over 150 since the bottom end is stock.

Big cams can pick up 70rwhp... something like the MS4 (239/242), EPS 236/248 111, Tick Polluter 239/244 112, etc. Lots of overlap. They will like nitrous as well.
Rule of thumb is 10rwhp is about a tenth and 1 mph. So, 70rwhp would be close to 7 tenths and 7mph, which would get you into the 10s.
