ACCEL's Performance HEI distributor is made entirely of new components – nothing is rebuilt or refurbished. It's a direct replacement for your OE distributor and uses the factory-type connector for effortless plug-and-play installation. The housing is CNC-machined for accuracy, and oilite bushings keep the centerless-ground steel shaft running true. Both the OE-style mechanical advance and the vacuum advance are adjustable. The red distributor cap is made from high-dielectric-strength thermoplastic and has brass male towers for superior conductivity and corrosion resistance. The cap also includes a precision carbon brush which mates perfectly on the rotor using a stainless-steel spring and brass blade. For even greater timing stability, the gear is placed on the shaft, limiting distributor endplay. A performance 4-pin module provides superior dwell control and triggers the ignition as low as 75 rpm for easy starting in any weather conditions. This distributor also includes a performance coil and an OE-type coil cover. Ideal for a daily driver or a high-performance street machine.
