1966 #1111090 389 2-bbl distributor has exactly the same centrifugal timing advance as the 1966 #1111078 389/421 4-bbl distributor.
0-4°@960rpm, 12-16°@2000rpm and 20-24°@4600rpm. Add to that 6° initial. They do use different vakuum advance though. 090 uses the #1116242 control, starts@6-8in/hg and provides max 20°@13-14,5in/hg. 078 uses the #1116243 Control, starts@8-10in/hg and provides max 20°@15-17in/hg. |

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
