OK, here's the situation- - - -I'm due to observe a forensic disassembly of a 6.2 liter V8 2011 Camaro engine. It's in a limited production "Indianapolis Pace Car" clone with 21K miles on it. Prior to its initial sale, it was retro-fitted with a supercharger by the selling dealer, and carried a GM factory warranty.
Fast-forward 21K miles- - - -during a warranty repair of some minor oil leaks at another dealer, the original owner was sold on installing a set of GM high compression aluminum heads, with 66.5 CC combustion chambers. It made 20-something miles at normal highway speed (not being hot-rodded, according to the owner) and the engine hand-grenaded- - - -broken connecting rods, BIG holes in both sides of the engine, and fire damage from spilled hot oil to the underside of the car. If my number-crunching is anywhere near correct, the engine was built up with over 12:1 compression, plus being supercharged. That combination looks like they built a bomb! The bottom end is totally stock- - - -sintered metal connecting rods and all!
