My info is from the 1966 Tempest Chassis Shop Manual.
The only difference is that your info is on distibutor degrees and my info is on crank degees, as iŽve found it is easier to check timing on engine directly than to buy a SUN distributor machine.
The crank turns two revolutions while the distributor turns one revolution.
This means youŽll have to take distibutor degrees times two.
