Break-in Period

I will agree with part of this; however, you have to remember that everything on the truck is brand new. This includes the trans, diffs, etc... I personally don’t think engines need breaking in because of the precise tolerances and maching have come a long way. Ask ECGS about break in when you order a diff from them, they have. A specific way to do it by varying rpms and speed.

 

Disagree with your math. Two decades means your last sentence should be "It's not 1998 anymore."

 

...The comments don’t need to line up mathmatically...

Both were independent statements.

 

Look up GM or Ford crate engine break-in proceedures.

Heat cycling of all of the different components is a necessary step. Step RPM loading. Positive and negative loading of the engine.

 

yea that 1,000 mile no-towing part on the break-in was tough. Took me all night that 1st night to get that 1,000 miles out of the way
