Magazine Excerpt:
"Callaway does some serious breathing on the SuperNatural LS1 V8 during the hand assembly process. Internally, the heads, pistons, rods, camshaft and crankshaft are changed or modified from the stock Corvette LS1, upping the horsepower to 440 at 6500 rpm. An engine dyno sheet is included with each Callaway C12."
