if your tune is good, it should be just fine.

 

Its kinda sad that the 6.0 will make more power in the K5 since it has LT's (block huggers in the Z) and running the truck intake which makes more power vs a factory LS1 intake.

 

Gotta run what will fit.

 

I have a 222/230 115lsa in my 6.0L 5000lb half ton. Tows the hell out of my 4K lb bay boat. With a good tune, you shouldn't have any trouble. I have a TVS on mine, but can still accelerate pretty smartly without getting into boost.

 

thats not a big cam at all for a 6.0. should pull pretty good.

The real wuestion is what cam is going in the 5.3 that you'll need a 4k converter haha..

 

Hey guys, ended up leaving the 6.0 in the Z and selling it.

Had some change left over and bought a Roush (same as SLP) TVS 1900 supercharger kit with less than 5k miles on it.

Finished installing it a few days ago and got it dyno tuned yesterday, very pleased with the results. Thinking about the LS9 cam now.....

 

Problem solved!! That will give you the power where you need it!

I would think about a custom cam for your set up, or look into something like the vinci trucker. The LS9 cam will be the most civil, but there are other came out there that will give up the smooth idle (i wanted to with my cam swap anyway... it was part of the attraction) or possibly a little gas mileage in favor of a little more power.

 

Actually I was kidding about the LS9 (the wink). You are correct though, if I were to change the current LS6 cam out for something else, it'd be a custom grind in the 0.600" lift range, below 225 duration, and a 114-116 LSA. But at this point I am pleased with the power and I'd like to keep the smooth idle too (hence the 'Ghost' nickname).
