I got a 2010 Camaro with a highly modified LS3. It's basically a race car. It still has A/C though! It has kirkey seats, a 5 point harness, open headers, and a lot of the car has been gutted. I just rebuilt the top end and threw in a new cam this past winter. 376 cu in, all aluminum (block and heads), stock bottom end, flycut stock pistons, 11.3-1 compression, Hi-Ram intake, a very healthy cam and some other goodies. I spin it to 7600rpm. Makes around 620-640hp at the flywheel on 93 pump. The cam makes it a nightmare to drive on the street with the 6 speed manual. It needs a built TH400 with a 5500-6000 stall.
