Is it reasonably possible to get to get the seat of the pants pull of a lq9 out of a worked 5.3l. I know anything is possible with $$$$ that's why I put "reasonably". I am in possesion of a 5.3l in my '06 crew cab now. As I have posted before I'm lookin' for more power. I was/am on route to all the bolt-ons and with heads and a cam. I would be terribly disappointed if I did not at least get the initial pull of my dad's ( 64 years old ) tuned SS. A 6.0l can be had for about the price of heads for the 5.3. So, in a nut shell, with a set budget, stick on the built 5.3l path or a slightly less built 6.0l. Thanks, Art

 

Just go the 6.0 route. No replacement for displacement. Plane and simple.

 

PLAIN and simple is right

 

Think of it this way if you were to mod the 6 liter in the same ways as the 5.3 then you have more power from the additional displacement. Once you start it's hard to stop. Don't ask me how I know.
