There's a break in manual specifically for the LT1 engine.
It does not contradict that text from the camaro manual.

You will note that the camaro manual says avoid full throttle starts and abrupt stops, it does not say to avoid full throttle at all times.

It seems some people can't understand plain English. They assume "avoid full throttle starts" means "baby the throttle", but it doesn't.

The engine needs load to bed in correctly, the LT1 engine break in manual is very explicit in requiring part and full throttle runs (up to 4000rpm and with in gear rundown) as being the correct procedure.

If you drive the whole of the first 1500 miles with less than 50% throttle then you'll end up with a motor thats not sealed as good as it could be and down on power.
Given the hundreds of dollars people seem to be willing to spend to gain 5 to 10hp, taking the 5 minutes to find and read the engine break in manual doesnt seem too difficult.

Credit to Matt for posting these, please note that these do NOT contradict the chevrolet camaro manual instructions, they are just more detailed. The youtuber in the video has made the same mistake and assumed the wrong thing about what the Corvette/Camaro instructions actually mean.;

"12. Change the oil and filter. Again, inspect the oil and oil filter for any foreign particles to ensure that the engine is functioning properly.

I skipped the oil-and-filter change in step 10, but did the one in step 12. I was at 700 miles when I did that one. Next oil change will be a the normal interval."

Therein lies the problem with using the crate engine break in procedure. The service schedule for the cars does not state changing the oil before the OLM systems recommends or 1 year (whichever comes first). Most dealers won't even change it before then period. So if we believe the owners manual process was wrote to avoid legal claims, then why not recommend a oil/filter change during break in like the crate engines? Surely there is a reason for the difference. And analysis of oil from break in on these cars (as well as most nowadays) shows no reason to change the oil early. So the facts do not match what many people believe. Could it be that the crate engines and production engines are built differently? I know I'd like to hear the reasoning behind the differences.

Personally I changed oil right at 1500 because I wanted to switch to Mobile 1. And I did follow the similar procedure on break in. But I don't think anyone can say the crate engine process is 100% correct for production cars. Because if there is one difference, there are likely more too.
