I would go with the 216/220

how can you tell me what rpm range these cams start making power.

The procharger will make more difference than any of the cams will. Since you have the procharger coming for real power, I'd go very conservative on the cam choice to keep your daily driver torque where you want it. I'd run with the 214/218.

so your saying the 214 would get me off the line the quickest with the 2600 stall. Giving me the best results in the 1/4 correct?

To be honest, the 214 cam is already big for the 5.3L compared to my standards, but I've gotten into many debates about my cam selection. I go after low end torque that pulls all the way usually past red line that can be used with the stock torque converter or something that stalls just a little higher...like your 2600. I don't like big cams that don't make power until 3000+ and redline at 8000+. The 214/218 will be a torquey cam down low and you'll have the procharger to do the rest. It's roughly a 1300-6500 rpm cam in a 5.3L and you have the supporting head modifications to take it all the way up there, so if I were driving your truck I'd opt for that cam for hard launches and daily driver manners. Let the forced induction take care of the high winding "play time".

Do you think my goals are realistic with my mods or is there something that I should change.

I'd go for the 214/218 of those choices, considering the 2600 verter. As Inch mentioned, the Procharger is going to be your biggest power maker. Personally, with the Procharger I'd probably go with less cam and converter, maybe a 212/218 high lift...just my .02.

216/220 or try the 212/218

With these cam's are my goals realistic?
