Curious. What's the difference between a 273 4 barrel & a 273 Commando? I always thought all 273 4 barrel engines were Commando engines. 4 barrel, valve covers, domed pistons, dual points, & different camshaft. Was there something else?
273 4bbl's aren't very common, most were Commando's
The finned valve covers, domed pistons, dual point dist and the bigger cam was on the Commando's. The 273 4bbl was just a plain engine 273 with a 4bbl.
