Competition V6/90º Chevrolet (229ci) engines with common pin crankshafts have an "odd-fire" sequence which alternates between 15º and 90º of crankshaft rotation between sparks. This odd-fire distributor is highly recommended for V6/90º racing engines equipped with heavy-duty crankshaft P/N 14044838. It has a lightweight machined aluminum housing, a hardened shaft, and a ground and hardened centrifugal advance cam. Its high-output magnetic pickup will trigger GM Performance Parts heavy-duty ignition amplifier P/N 10037378. This distributor uses a small diameter cap and rotor, and it will clear most competition induction systems. A selection of advance springs and bushings are included to allow you to tailor the spark curve.
