Factory engine break-in?
I read somewhere a while back that the Corvette engines receive some sort of break-in procedure at the factory. I searched the forums but couldnt find any relevent info. Does anyone have any info on this or know where to find some reliable info? Thanks in advance guys.

I'm not sure if they break in or even run the engines before installation. What I DO know is that the 2009 Owners Manual now has a rather detailed break in procedure that takes up to 1,500 miles. You can Google a copy.

Thanks for the input guys. Im not new to the performance game and always "break-in" my engines by varying RPM and load for about 600 miles. I dont rag on the car, but im not babying it either as I feel this is the best method. I currently have 200 miles on my 09 Vette, so still several hundred miles before I rag on it. I will take a look at the owners manual tonight. I have been breaking in the car as if it had never been driven before, but was just wondering about the factory procedures. I have to say, if the first mile or two the engine is ran is when it is loaded on the train, then im pretty worried...I used to go to school with several guys that worked at the local train depot where the new cars come into Tampa, and they always talked about ragging on the new cars and doing burnouts...

I would be nice to it but also "train" the car to act aggressive. ALL cars these days are Modular learning in every aspect.
After you tune a vehicle, it has to re-learn parameters etc.

Worst possible break in procedure on a new engine is the "drive it like you stole it". Second worst is to baby it.
First 20 miles (or at least during the first 100 miles) you need to load the engine (not full throttle) with moderate acceleration in one gear up to 5k rpm, then back off with engine braking. Repeat, repeat. This sets the rings. The rest of the engine is still very tight. Multiple oil analysis's done on these LS engine show that they are still wearing in well past 10,000 miles. Change the oil between 500 and 1000 miles (sooner if you want). One oil analysis company recommends every 1500 miles until you reach 10,000 miles. After the 500 mile drivetrain break in is done, drive it as you want, but the engine is still "wearing in".
