Sold a bolted 2.0 Cobalt SS LNF two summers ago. It was 360 whp/400 wtq and ran 60-100 mph in 4.6 sec. About 1.2 sec faster than this SS. It weighed 3k lbs though, not 3800.
Hard to launch & get traction on wrong wheel drive.
I think a turbo DI 6 would be ok in the Camaro. Should be 400 hp easily.
Another 1 of 371 '12 T3 LS3 M6's built.
