I found this forum while researching the SSR before purchase. The forum answered most of my questions and I was able to eliminate my fears. I found a redline 05 vin #19837 born 12/04. I read the manual about engine breakin and have behaved myself for 100 miles. Question is, what is the best way to breakin an Ls2 engine. The truck is great, beyond my expectations and is one of the most fun cars I have to drive. thanks.
