Hey everyone I'm new to the forum, I'm Ray from south Florida. I have a 02 Yukon with a 5.3L with about 155k on it. So I am now in the market for a 6.0 to replace my aging 5.3. I will be purchasing this ahead of time, and mounting it on my engine stand to install some upgrades.
I know you guys are good with the performance aspect of these engines and would love some suggestions.
I don't want to go too crazy, I will be towing, and I will be using it as my daily driver. I was thinking about a supercharger or turbo in the future, but I'm also looking for reliability...
I'm looking for any and all suggestions...
I will be changing out the tranny, was thinking about an aftermarket but I'm still researching.

 

Hello and welcome again Ray.
I see a 6.0 with a Magnuson supercharger, followed by a 4L80e transmission in your future. Just those 3 things will put your truck in the high-power department with stock reliability.

 

Agreed!

 

You need a single front mount 76mm with a polished housing and polished tubing. maybe a fast manifold for added performance and looks.

 

How about a nice cam to go with the huffer that trever1t mentioned, like the Lingenfelter GT2-3?

 

TVS 1900 with a level 5 4L65E.

 

Throw a 350 in it..........




Cool matching paint.

 

Sweet truck Ray!
Aging? lol you'd be good for a long while yet if that truck's been taken care of

 

why not a 6L90E?

 

Thats the thing, I am hard on everything I have. That truck has seen WOT on average 3 times a day since I got it back in 01. I don't want to change it b/c I think it will quit on me. I want to change it out b/c I want a 6.0, and maybe even get a little back from my decent 5.3.

Anyone like any turbo set ups for these engines? Just curious what the pros and cons are of either set up, supercharged or turbo.
Also should I be looking to upgrade anything else if I do a supercharged 6.0? Will I start breaking stuff down the line with that much power?

Thanks Guys
