ID 273 Commando that's apart

In addition to the valve covers, a Commando motor has a 4 bbl. manifold & carb, domed pistons, different camshaft, chrome air cleaner, valve cover breather cap & PCV valve holder, & a Prestolite dual point distributor. I think that's everything.
The 4bbl pistons have a lighter piston pin too...just remembered seeing the 2bbl's as HEAVY walled pins.
