Hi I'm dusty, Long time reader first time poster!! hahahahaha

Soo I have a ecsb,HP tuners, home made cai, cherrybom vortec duals, no stall, 3.73s, and 285/70/17s and I pull 8000lbs in the summer almost every week end.

my question is, Which cam will work best? off the line I'm not worried about yet (that will be a 6.0 and 4l80 swap with 4.10s or 4.56s) just looking for experience, knowlage and any input. Thanks for any!

sorry typo!!! I'm not worried about off the line just yet then it will be a 6.0 swap.. my bad lol

 

those some small cams with a 6.0 u can go much bigger with towing

 

If you're set on one or the other, go with the 212/216, in a 6.0...

I went with the next size up comp cam, the 216/220 .525/.532 in my 5.3 and it drives basically like stock on the low end, I also put on Lt's and a full dual exhaust, so I would have lost even more low end with those... in a 6.0 I'd expect you to still most likely gain a little on the low end for your towing.

I don't see why you couldn't go all the way up to something like a tr220 or 224 and still not have a problem towing with a 6L

 

This has to be asked atleast 3 4 times a day..

This works pretty decent

 

It was only a matter of time until this happened.

 

its going in a 5.3 will be swaping a 6.0 some day later on. t ryed the search button couldnt find anythin on the first cam.

 

get a 218/222...They might have one for sale on here!!!

 

i would use one cam for the 5.3 then get abigger on for the 6.0.. but thats just me.. on my 5.3 i love the 217/223 549/549 113lsa i have.. best 1/8 of 8.62@80.62mph for a 6.0 i would go bigger like a 222-224 duration..

 

You can't go donkey dick on a cam, expect it to pull 8k decently.. keep it on a split duration, in the 21x-220 duration
