Only if you measured all the relevant parameters before assembling it: Bore, stroke, piston deck height, combustion chamber volume, cylinder head gasket bore and compressed thickness. |

You need to dis-assemble and measure everything in order to get an accurate static compression ratio number. For an assembled engine, test the dynamic compression ratio (cranking pressure in psi) and "leak-down" rate... that can tell you a lot about your combination. DD |
