I bought my truck and it had about 300miles already on it. I'm pretty sure those weren't all "nice" miles. I had the boat hooked up the next day. lol

I waited until 1k miles to flash a Livernois tune on it. Probably only had 600 on it before the cat back was installed.

I am sure when people test drive a car they ain't going to "baby" it. When I test drove the truck I have now I will admit I smashed it going up a on ramp.

You have an hour to "break in" an engine. Once its up to operating temperature, pushing it hard and bursts up to redline will ensure the rings get seated properly.
I wouldn't do sustained high speeds and rpms, but hard loads will get the engine "broken in" and parts meshing. Finding a steep hill and coasting down at moderate rpms under no throttle (engine braking) is also beneficial.

Babying your engine makes you feel better, but has no benefits to seating those rings!

There is no break-in period. Zero, None, Nada, Zilch

Your manual disagrees with that. No towing for 1000 miles

That isn't because the engine needs to be broken in but rather the computer is working on learning shift points and mixtures. Doing this under load would be problematic.

You can baby it you want and read what you want in the manual. Race engines are built and treated on the track with no respect. Drive it like your gonna drive it right off the lot. Unless it has 0 miles when you buy chances are it been to the floor. I have over 40000 miles on mine now and it's been run hard when I wanted to and babied a lot with zero problems. Drive it the way you want and if it breaks it has a 60000 mile warranty.
