Speedmaster Thunder Series HEI Electronic Distributor Small Block and Big Block Chevy

Procomp Electronics Thunder Series HEI Distributors are a favorite for muscle cars, street rods and even circle track racers. The integrated coil keeps underhood wiring clean, and for race cars, the idea of running one wire to the distributor keeps things simple. When it comes to performance, the Thunder series answers the need for a strong, accurate and high performance HEI where the stock HEI falls short. Tig welded on top of the distributor shaft is an adjustable centrifugal advance assembly. The Vacuum advance canister, improves economy while cruising, for those concerned. All of this is assembled around a precision and great looking CNC-machined housing. The distributor features a 65,000 V coil and is supplied with thunder cap, rotor, coil cover and heavy duty gear so it is ready to install in your engine!
