10.5:1 Pistons for '66 273 Block w/ '67 920 Heads

I too used Egge high compression pistons in my 273 build. With the stock small chamber 273 heads and a thin head gasket, I ended with 9.6/1 compression. Call Egge for more info. The pistons were very good quality and very consistent size and weight. The link to my build is just below here. tmm
