This Gen 2 Dual Sync distributor is built for sequentially injected Pontiac installations, though it can also serve as a crank trigger for a TBI system. Dual Hall effect sensors read both crank and cam for sequential EFI operation, and the billet aluminum housing includes a QPQ-coated shutter wheel that's pinned and welded to the shaft for long-term reliability, even at high RPM.
