I've got a Circle D Billit Tri Disk 3400 behind my 383ls and it works good for daily driver duty but the stall is not your lack of power issue at all, Did you degree the cam?
If not I'd install that cam in a low compression 5.3 at 110* a 114lsa with 224-228 duration with 220cc heads and small cubes should just about suck in the low end rpm range, especially if its on a 116-118 intake centerline! Personally i would use trick flow 205cc heads with a cam in the area of 216-220 on a 110-112lsa and mill the heads with thinner gaskets to get over 10-1 compression, JMHO

Pontiac Derek its a 114 lsa cam and stock compression ratio
with prc 2.5 heads and i dont think i wanna change the heads neither the cam
now one important thing i forgot to mension
the car is 2011 model so it does hae both dod and vvt
i did cancel the dod and did change the cam gear to the old style 6.0 cam gear to match my 3 bolt cam
but i didnt change the timing cover ! to start the engine im having an issue with starting it sometimes i have to start it 5 or 6 times to run the engine !
a friend told me that cam position sensor is diffrent in vvt engine and the pcm doesnt recognize the signal coming from it so i have to change it to ls2 or ls3 timing cover
i hope this timing cover will solve my problem and give me the right cam power cuz im having only 30% or less of the cam power .
so tell me guys ur opinions plz

Yeah LOL the Cam Position Sensor isn't working LOL ok yeah i'm not sure you can use 3 bolt stuff with the factory cam position sensor, early ls used a cam sensor in the rear of the block, i'd just get a single bolt cam and put it back together
