abc...reminds me of when I bought my first SS396 Camaro. It was a one owner with 10,000 miles on it. I went over the the owner's home with my Dad ( I was a young billy goat then ) and the owner and I went for a test ride. He drove the car about two or three blocks very carefully. ( out of earshot of my Dad waiting back at the guy's home ).
Well, he looked over at me and said, " Is this what you're looking for?" as he proceeded to nail it in second gear at about 30mph. The 350 hp 396 made a lot of noise, the tires smoked and I was a very happy little goat as I was plastered to the passenger seat. ( strange how those old iron big blocks could make so much hp and torque without even ONE microprocessor-the 101 octane av gas sold at the pump then didn't hurt ! )He told me this was the way he had broken in the car from day one.
I enjoyed the car for years and never had any trouble with the engine. The guy I sold it to for grad school expenses noted, however, that the clutch was toast....
So how to break in an engine as gee whiz as the LS2? I dunno. For all the real time computer engine controls, fuel metering, spark coils on each cylinder and what not it still has pistons running in iron sleeved bores to make power. Is an LS2 really that different from an old hi perf V8? I kinda think I'll follow c5vetter's approach. It will get babied for 20 miles or so and then....if it doesn't break it's a keeper.
However, you break in you new C6 have fun you lucky devil.
