edit: just read my own post and realized it could be taken harshly...that statement isnt directed at anyones specific dyno numbers, but ive seen quite a few cars/trucks put down massive numbers and run like a pile of crap, then others drop lower than average numbers, but run like a bat outa hell.

On the other hand the smaller cam will make more usable power at a lower rpm.

I noticed even with a "small" cam the gains don't show untill after 4000rpm

The cam in the 5.3L in my Avalanche (with a stock converter) was a 205/212, .544/.550, 114+4, and it added 15-20 RWHP/RWTQ across the entire powerband. You won't hear many guys admitting they want a cam is this small, but I don't (and didn't) care what other people think. It gave me the exact results I was looking for -- more power under the curve from idle all the way to redline.
If you want to race your truck all the time, have a high stall speed converter, and/or like living in 2500-3000 RPM and above, then you should get a bigger cam. However, if you are like me and want all-around, daily-drive power, then you might want to consider something a little more mild.

They said that in a 5000 lbs truck the 224 cam will be a complete terd and a 210-218 will be an animal all the way to 6000 rpm. Let me know what you guys all think about this. I Know I know another cam thread. But you opinions are apreciated anyways, Thanks, Jared
RPM range can always be matched with verter speed if your runing an auto.
