Compression ratio with Silvolite 1267 pistons and stock heads?

With the 1267 (same as mine) compression height of 1.824, those slugs should be pretty close to zero deck +/-. Once you get your actual chamber CC (mine are 69CC) do the math. With the right cam you can dial in an acceptable DCR for pump gas. My static cr turns out to be 9.17 with an .040 head gasket. My cam choice puts me at 7.75 dynamic cr.......Should be great for the street with 3.23's. Good luck with your build.
