Can I put the headers for a 5.3L on the 6.0L? I was told of this on ebay, from a guy selling some pace-setters for it. He said they would fit both engine sizes. Is this true?
They do look similar...

before buying make sure headers will not cause problems with the knock sensors.........

Got me there... why is that?

j cAT

the knock sensors may pick up noise from the headers this will then retard timing... then the pcm with knock sensors may have to be tuned to this new configuration.....these vehicles are not happy with aftermarket performance mods.... so i repeat make sure any aftermaket add on is going to no cause problems....it may fit but will it work????????

That's What I Thought. Thanks For The Reply. I Will Try To Get One Pair For Mine Soon Enough. Although Pace Setters, I Believe End Effect Will Be The Same.
