273 commando

To confirm it's an actual Commando, you'll have to check to see if it has the 10.5:1 hi-comp pistons, etc, that all true Commando's came with.

Correct, the blocks, cranks, rods, heads are all the same.
Commando = Pistons, cam, intake, (valve covers, carb, distributor, air cleaner...)
