Maximum Compression Ratio

I broke a 340 when I was younger by running a nice lady's old lawnmower fuel in it because I ran the car out of fuel in the middle of nowhere. Ah to be 17 again... anyway the bits of ring land and piston I keep in a little plastic baggie over my work bench. It's been moved from my parents house to two shops to my current home. Sometimes the best learning comes from making mistakes.
