WOW 
This is about helping someone with a cam choice, not shittalkin about my scan.
I'm trying to show that my motor with a small cam makes decent torque at low rpm and that it would work well for his needs.
Everyone knows the #s are not accurate in the scans, just like I said in my post.
FWIW, CONSERVITAVELY cam=20, LTs=20, tune=20 +330 stock =390
Even if the scan is 20+ high, it shows some nice useable torque with over 300 at 1200 rpm.
You guys know a thing or 2 about cams.
How about adding some helpful info.

Lol. I wasn't **** talking about your scan, I understood what you were saying. You were just trying to show the difference in TQ. It's no different than a dyno that reads high. You get a base number and then you get an after mods number. As long as you use the same tool to measure the power you can see the gains. Even if the total numbers are wrong the gain should be close to correct. Richard knows his stuff. If he says that 210* is the point where you need a stall then I wont argue that. I had the 210/218 and a 6L, 2600 stall, +Radix. Power under the curve was not really an issue for me
I surely wouldn't go over a 220/220 without a bigger converter but I think a 210/218 would work well. Hell, the Vinci ULTRA TORQUE cam is a 210/218.

but how do you figure stock torque is 330? It's nowhere close to that even with your HO 5.3LWith that said, I would go with the 210/218 .551 lift cam. I know of several lifted guys who run that cam without a stall and they love it.

I've lived with a 5.3l with a cam just a tad bit larger than 210º. Even had 4.10's and the truck felt soggy when launching. Once the tach swung past 2300 rpms the engine pulled hard to 6000. It was also weak when cruising on the freeway with the converter locked. At 65mph the tach hovered at 1800rpms. Applying throttle didn't accelerate the truck much. A 6.0l engine can swallow a 6º larger cam before suffering loss of idle/low end torque. Once we added the Yank 2600 it helped the launch big time, but cruising with the converter locked at freeway speeds was still soggy especially when towing.
As mentioned in his original post, he doesn't rev the truck past 4000 often. Definitely keep duration under 210º and definitely add the LT's. You'll love the way it drives.
Good luck,
Richard
