Thanks x. Much appreciated.

I need the crankshaft out of the engine for balancing.

I need it to run on pump gas. I found it interesting that changing when the intake valve closes lowers your static compression. Making it possible to run 13:1 static CR without changing your ignition timing.

I don't need to calculate it, just interested in what Dynamic CR with what timing enables pump gas to be used.
