360 LA turbo exhaust question

anything is certainly possible. Guess I will find out once I pull the heads. This engine was probably a 9.5:1 NA engine. I had no detonation (that could be heard). I had it running around 10:1 under full load.... was actually going to tune it out in the sand and slowly pull fuel out.

I just figured piston land because something hit the spark plug to make the center electrode touch the grounding electrode. The plug looked normal other than that. The pistons are Hypereutectic and have no idea what the ring gap was set to. Built this engine 12 or so years ago.

At any rate, new engine will go in and it will be far better suited for boost.
