Is it possible for 318 to run with dist. 180 deg. off ???

Just read on the Hughs site how to set up cam timming and it says as per all manuals crank dot to 12 oclock and cam gear to 6 oclock ! But to insert the distributor in you must turn the engin over one more revolution as this will have the distributer at number six so one more turn of the motor to get dissy at number one. Hughs blames Al Gore for this as he says it has always been like this so must be Al Gores Fault!
