Prior to 1972, Ford used dual-point, mechanical-advance distributors in high-performance applications like the 390, 406, and 427 High Performance, the 289 High Performance, the Boss 302, 351, and 429 V-8s. In earlier applications like the 289, 390, 406, and 427 High Performance V-8s, the C5OZ-12127-E dual-point distributor was a mechanical-advance only for high-RPM use.Donate Blood,Plasma,Platelets & sign your DONORS CARD & SAVE a LIFE
