I need to cc my chambers because 74 would be a lot different than 64. My calculations with a 64cc head show a static compression ratio of 9.3 with 18cc dished pistons, if I go with 7cc flat top pistons the ratio jumps to 10.4.

Tuts 59, thanks for the idea of measuring the cab location before I remove it. I may still want to put the cab back on before I lock the engine location down but it will provide another degree of certainty.
