Hey guys i just got a 2011 z71 rcsb! I was wanting to buy an LS car but the truck seemed to fit what a need vs what i really wanted but i have to say I'm happy with it anyways, after all still lots of potential!

Anyways to the point of this thread, I am wondering what is most cost effective, and better in the long wrong? Ive narrowed it down to A. Building the stock 5.3, FBO H/C/I plus nitrous, or doing a 6.0 swap? 6.0 would eventually be built and most likely N20 as well but over a slower time period do to the cost of the swap itself.
I personally prefer a mean N/A engine, but at the end of the day what are my main differences as in HP, TQ, 1/4 mile times, drivability, etc..
Thanks guys!

Just use what you have, atleast that's what I would do.

Your cylinder heads are already some of the best ever made for stock motors, not even worth upgrading. 799's are just that good.

Stock intake is great too, flows likely more than you'll need on the 5.3.

Do a cam swap, delete the DoD/AFM stuff and get some headers. Then tune it and slap some nitrous to it. Then prepare for the rear end to break lol.

Imo, buy a 6.0 short block, add a cam and throw your current heads and intake on it.

I loved my 5.3. I did add some tf heads and a fast intake when i was NA then did a Victor JR when i went n2o....I did drive it alot but dam not very street friendly lol in stop and go traffic then again i had a 4600 stall once it locked on the expressway was alright
