Been a while since I been on PT.net since I sold my old blue turbo silvy but im working on a new project and need some cam advice from the experienced guys..Ive got a 2011 sierra ccsb 5.3 that i had planned on just doing a VVT/DOD delete, my Tu0 216/216 .561/.561 114 cam, and my PRC stage 1 LS6 heads and call it a day. Well I stumbled on an gen IV LY6 shortblock and have decided to rebuild it(stock) instead of messing with the 5.3. Notice I said shortblock so I don't have the square port heads and I will be using my Ported PRCs and my stock NNBS intake. My question is should I use the 216/216 Tu0 I have now, or possibly go up to a 220,224,228 etc cam? Its a DD and I don't plan on a converter as of now... and as you NNBS guys know.. 6l80e plus 3.73's is crazy low in 1st gear lol Here is a rundown on the truck now

2011 GMC Sierra CCSB
6l80e stock converter
3.73s(swapped out 3.08s)
Pacesetter LT's/ORY
Blackbear Autocal tuning


Thanks in advance guys

 

I DD'd a Torquer V2 for a long time, I also had the 224/230 .581 .592 -110

Your LY6 has already has valve reliefs cut into the pistons . . . . go nutty since you have ported heads.

 

Only thing that scares me on a cam that big Matt, is the stock converter I plan on running for a while...

 

Stock converter is liniting factor so i would just put that 216 cam for now.

When you decide to stall at least 3200 , then id see about a 228 232 cam.
