Keep in mind this is STD numbers and your SAE will be 5-10 hp lower. Maybe you have a vacuum leak somewhere, that would cause idle issues, or if you are running in closed loop you could have an exhaust leak before your o2 sensors. I highly doubt your cam is off a tooth as the power / torque curve looks spot on. Try to check your IAC motor on the throttle body, they get plugged up with carbon after a few years. Clean the thing out with some brake cleaner and that may help. What exactly is wrong with your idle?
guys this is my actual cam so we know it can make power... 
and for the idle it should have no problem at all right around 900rpm...it was actually a great street cam...
I hope when you installed it wasnt setup wrong I know it is easy to get mixed up with advancing and retarding the cam with an adjustable timing set...the cam is a 111+4 but I retarded it 2* to get it at 111+2 to gain a hair more ptvc...now it can still be installed straight up and have tighter clearance and push the curve a hair but I think the power is a little on the low side if you have full bolt ons and locked on the dyno...
too bad you didn't do a baseline cause that would help out a ton...

well if I check to see where it was installed at and it is straight up... do you ahve any more ideas on what I should check??
I think that is the route I am going to take as of now... Just to make sure that it is lined up and then go from there.. I really thought I would hit at least 400rwhp...
It still wants to die at certain times.. while driving and then coming to a stop some times it will die and other times it is fine.. I also didn't think that I would have to my idel at 850 either... thought I might be able to get it lower than that but if it is any lower the car will die more often.. I will check out my IAC and see what I can find there...
this is very true.. but really am I gonna be able to run mid to low 11's with 375rwhp?? I guess I just really wanna find out if something is wrong with the car or not...
I know that it sucks cause I didn't have a baseline before... I belive the same thing about my low numbers with what I have done while the converter was locked...

no on both
no I'm just saying that I wouldn't think that it would have to run the idle at 850 to keep the car running... and even today with what little driving I done.. when I was coming to a stop my car died on me... it doesn't happen all the time but some times...

since the car has been tuned I can tell a little more grunt down low... but there really wasn't that big of a difference from having the new cam installed and tuned before the stock one...

an idle at 850rpm aint bad at all. Try raising it to 900 it should idle a lil smoother.

I had to have my idle raised up a little to avoid stalling. As far as dynos go its a tuning tool. The track will show what you are really making. When you get things sorted out is that invitation to race still on?

if he has a 3400-3600 stall converter, wouldnt his tq graph look a lil different below those RPM's??? maybe the TC isnt really a high stall unit and is actually too tight which is why its having trouble idling???? i have personally experienced this problem in my Galaxie. I was sold what was supposedly a higher stall TC which turns out to be what i think is a STOCK STALL TC. All the cubes (533ci. with 260/269 solid roller .650/.650 low lift for spring longevity) keeps it from being a turd down low and it surprisingly runs well (still has traction problems with street tires) but it does have noticeable trouble idling when not in neutral or park. I wouldve tried getting my money back for my TC BTW but i didnt even install the engine and tranny for well over a year after buying the TC.
bottom graph is cam only...
top is new heads and cam

looking at his dyno graph both your guys cammed cars are done by 6800rpm although yours peaked at about 6300-6400rpm
interesting thing to note
@3500rpm he produces 30+tq
@4000rpm " " 30+tq
@4500rpm " " 10+tq
@5000rpm " " 5+tq
@5500rpm " " about the same
@6000rpm " " -25hp
@6500rpm " " -30hp
@6800rpm " " -20hp
