Commando 273 engine block crank etc
Casting number on the block please? (just to make sure it's a 273)
All 273's used the same block, crank, heads, rods and valve train. The Charger/ Commando engines had different pistons, cam, intake/carb, and a dual point as well as valve covers and air cleaner. Regardless of which intake this has, Nothing sold here could be from the HP engine except for the cam which may be reground if reused.
@Jgirvalo, you should probably delete "commando" from the description.
