VR1 Valvoline 10W30 oil for classic muscle cars. Enough zinc to protect camshaft. Might even try the Mercury 10W30 4 Stroke marine oil. Engineer i know said this oil has even less zinc then the VR1 Valvoline 10W30 oil and the Mercury out performed the VR1 in testing. Engineer told me to much zinc can actually cause wear in a engine.
