Yes, I was wondering what C/R ratio pistons Tom installed - so I probably should have asked the question that way. I was targeting about 10.5:1 given I have a stand alone ECU that is completely tunable for ignition advance (so I can be conservative with setting that impact knock).

Tom, another question, is the block you build safe to spin to 7,500 - 7,600 RPM?
