In a 135.5mm deck height Tillotson Racing block with a 63.5mm stroke crank, the 3.525" length stroker connecting rod, and the .550" compression height optional size for this piston it will sit 0.010" below the deck at TDC and create a 288cc short block. Add a cylinder head with a 16cc chamber with a 0.045" gasket under it and you'll have a 14:1 compression ratio. As an example of what this combo could do, you will need a head that flows an approximate average of 150cfm to be making power at 8,000rpms with this large of an engine.
