Max Compression Ratio for 5.4 2V
Hi All,
I'm nearly ready to choose pistons for the rebuild on my 5.4 2V from my 2004 F250.
Machinist is doing the bottom end to recover a 'mild' spun bearing.
Any thoughts or experience on the max Compression Ratio that should be run with this combo?

To much needed info here to make a recommendation....machinist would be your best source as it depends on altitude, fuel type/quality, cylinder pressure, cylinder head milling, head gasket thickness.
