    CR Example

     



    Ran across this engine example at smokemup.com

    The guy bought a short block with the specs in the table below.
    Static compression looks is low at 8.71:1. The story is he entered .0025 rather than .025 for the deck height and miscalculated static CR.

    I entered an arbitrary cam angle closing of 30 degrees ABDC and the result I believe is a fair pump gas dynamic CR.

    Assuming the numbers are correct (ya'll let me know if they aren't), what's the next step in finding a cam that will run in this motor or is it a lost case?
