RE: More than one advance curve for 427?!?

By Dave Shoe - 04/06/2001 8:42:49 PM; IP 216.243.158.9

I just checked my 1966 Ford shop manual (Aug 65 printing), and it lists the exact same info as the 1965 manual, but adds that the 427's 1966 distributor was a C5AF-12127-F - apparently unchanged from early 1965.

1961 crank timing (all 352/390):
3 deg, manual trans, 2 to 10 deg allowable limit
6 deg, auto trans, 2 to 10 deg allowable limit

My 1961 Ford shop manual also shows the 390HP got a C0AF-12127-J or K distributor:

Set test stand to 0 deg @ 250RPM and 0 inch vac
650 RPM: 2.25-3.25, 0 vac
800 RPM: 5.00-6.50, 0 vac
1125 RPM: 7.75-9.00, 0 vac
2000 RPM: 11.50-13.00, 0 vac
Max adv limit 14 deg
