1969 Dart 340 cam selection help !!!

Rob, there are some aftermarket OTC pistons from other makers that will yield approximately 9.5:1 with 68cc heads (naturally, dependent on deck clearance)...I wanna say DSS makes some, I bought their pistons for my 4.6 4V-real nice pistons.

There they are. Math says they'll come to .020" below nominal deck height. If you zeroed it and ran an .030"x4.1" gasket, it would yield 9.5:1 on the money with those pistons and a 68cc head...
