66 fender tag decode, think I have a clone

The Commando package had a higher compression ratio, bigger cam, 4 bbl intake/ carb, chrome air cleaner, crinkle painted valve covers with aluminum raised sparkplug holders, and a dual point distributer.

Have no idea about the compression or cam (easiest way to check to confirm), it has the 4 bbl intake/ carb, chrome air cleaner, crinkle painted valve covers with aluminum raised sparkplug holder, will check tonight about dual point.
