I have an 02 z28 w/ 4k miles. At what mileage will the LS1 achieve max power and mileage?

 

Here's some reading materal for you http://www.sallee-chevrolet.com/Info..._break-in.html If you have 4,00 miles on it it should be broken in, take it out and give it hell

 

30,000miles, or 50,000kms

 

30,000 miles I puled my stock motor out for what I have in my sig with 29,000 on the clock guess it wasen't even broke in yet.

 

They do take a relatively long time to break in.

 

Go run an open road race. When you cross the finish line it'll be broken in

 

thats for an older engine with a distributor

 

Other than adjusting the distributor and carb, what has gm changed about their break in procedure with the lsx?

 

And what does the distributor change in regard to break-in? There's nothing special about the LS1 or other GenIII motors when it comes to break-in. They are still internal combustion, ohv, pushrod motors. At 4,000 miles, it's as broken-in as it's ever going to be.
