RE: Advance Curve for 427 dual point dis

By Dave Shoe - 04/05/2001 8:12:48 PM; IP 216.243.158.186

Crank timing 8 deg BTDC.

Centrifugal advance. Set the test stand to 0 deg at 250 RPM and 0 inches vacuum.

650RPM: 2-1/4 to 4 deg advance, vac=0
750 RPM: 4 to 5-1/2 deg, vac=0
1000 RPM: 7-1/4 to 8-1/2 deg, vac=0
1600 RPM: 9-3/4 to 11 deg, vac=0
2000 RPM: 11-1/2 to 13 deg, vac=0

Max advance limit: 16 deg

From 1965 Ford shop manual, printed Sept 1964, which indicates it's for a 427LR.
