I am assuming uou are running an automatic trans. You are going to need a 3,000 stall minimum for that cam. Cam is also really too big for stock Vortec heads as well as the compression ratio you will be at. Finally the stock intake manifold will choke that engine off from making power over about 5,200 rpm. I personally would back up and punt. I would not go over 220* intake duration with 210* being preferable. About 8-10* more exhaust duration than the intake. GM has a great little cheap roller cam made by Crane.

That being said I can give you some guidance on tuning what you have but I feel you will never be happy with that cam in your mostly stock 5.7 Vortec.
That cam is going to want ALOT of air at idle. First I would open the throttle plate minimum air set screw about 3 turns. Then using a scanner with the key on and engine off back off until the TPS reads Zero. From there raise your warm idle speed to about 1,000 rpm. Start with about 1,600 rpm at the coldest value and smooth it down as the temp increases. Set your idle airflow in the warmed up portion of the Park/Neutral to about 15 gms/sec. Set your In-Gear to about 18 gms/sec. I would bump the coldest temp values about 10 gms/sec and smooth the table down to the warmed up value. I had a similar cam I tuned in a 5.3 and had to drill a hole in the throttle plate to get it to idle in gear. The IAC could not bypass enough air to maintain idle speed in gear with the much lower than stock idle vacuum. Set your idle timing table to 26° in the 0-1,200 rpm range from 20-70 kpa and taper down to about 20° at 100 kpa. Finally set your MAF high fail frequency to Zero and set the MAF high code to set a DTC on the first failure. That will disable the MAF and allow you to tune the VE tables. That cam with its abysmal dynamic compression ratio is going to want ALOT of timing in the lower RPM range. I would set any timing value less than 20° to 20°. in the 90-105 KPA range, 20 @ 400-1,200, 22 @ 1600, 24 @ 2000, 26 @ 2,400, 28 @ 2,800, 30 @ 3,200-redline as a starting point then interpolate the values across from about 40 kpa for each RPM row. Should see higher numbers throughout.
EDIT- I forgot you said 0411. Disregard the KPA, I had Black box in my mind. Will get back with you on a timing map in Excel.
