273 commando Build

Finally got the fish out of storage . I checked the compression on the commando with a new gauge and it is 150 + - a couple . Good thing.......... I've been running 93 octane . probally some where around 10.1 compression .
With 150-ish and a medium cam...9.3-9.5. Not unusual for Mopars to show 3/4 less point than advertised by Mopar.
