HEI systems provide a more powerful spark to the spark plugs, allowing a wider plug gap for more complete ignition of the air/fuel mixture that has been compressed in the combustion chamber. The system is remarkably simple and dependable, with a direct mounted ignition coil and only requiring a single key switched power connection to function (with a properly grounded engine block of course). This eliminates the external coil, coil mounting bracket (and the room for it), any resistor wire or ballast resistor, and the wiring between the coil and distributor. Due to the popularity of the GM HEI distributor, there have been numerous versions sold online over the years, many of questionable quality. Often, there is no way to easily source their GM HEI distributor parts to keep that bargain Chevy HEI distributor you scored online somewhere in running condition. Now it is no longer a bargain when you must shell out more money for another HEI distributor. We aimed to solve these problems when designing our HEI distributor by using quality components, precision manufacturing, and easily serviceable parts. From the standard 4-pin HEI distributor module to the HEI distributor cap, and more, we stock everything you need to freshen up your Speedway Motors HEI distributor for years of trouble free service but in an emergency, you can source replacement parts from the nearest automotive parts chain store. Built Right, Built to Last, and Easily Serviced Anywhere We start with a CNC machined and highly polished aluminum housing that is fitted with a performance ignition 4-pin HEI distributor module, high voltage coil, adjustable vacuum advance unit, and more. The mechanical advance can be fine tuned using a , but for most street applications the mechanical advance curve fitted will work right out of the box. The 4340 chromoly steel gear fitted to the distributor shaft is compatible with cast and billet steel cams. Our HEI distributor fits all small block Chevy V8 engines and standard deck big block Chevy engines (such as 396, 427, and 454 displacements), making it the perfect BBC distributor. We think you’ll agree once you have our performance HEI distributor in your hands that it is the best HEI distributor for the money. Our performance HEI distributor can be used as a replacement for a stock HEI unit, or as a retrofit from a points based ignition. We include our GM HEI distributor pigtail to make power and tach connections easy and more secure when converting from a previous ignition system such as the original points setup. Furthermore, due to the HEI style distributor cap terminals you will need to update your wires to the appropriate HEI plug wire kit, so to make things easy we’ve added one of our top selling Moroso 8mm spiral core plug wire sets to this kit. Complete Your Ignition Upgrade with Plug Wires And Multi-Strike Ignition These red ignition wires include the proper HEI terminal ends and are pre-assembled and ready to install on your engine. The plug wires included are designed for “under header” routing, which offers a clean appearance and keeps the wires out of the way. While you’re installing your new distributor, ditch that tiny stock distributor hold down for something with some real grip, like our extra heavy duty . To complete your HEI ignition system upgrade we have included MSD’s budget friendly Street Fire series capacitive discharge ignition control unit in this kit. The MSD Street Fire ignition features modern electronic circuitry, higher output spark energy, and multiple spark output through 20 degrees of crankshaft revolution and up to 3,000 rpm. The MSD Street Fire also includes a built in digital rev limiter easily set by a pair of rpm indicator dials. It is the perfect street ignition upgrade and works extremely well with our distributor and pre-terminated plug wires in this kit for an easy and trouble free installation on your vehicle. Charts (PDF) (PDF) (PDF) Installation Tips Distributor cap diameter is approximately 6 inches, determine firewall clearance before ordering. Factory resistance wire or ballast resistor must be bypassed or can be used to trigger a standard to provide power to the MSD Street Fire ignition control unit, otherwise a new 12-gauge wire from the ignition switch or a hot in start and run fuse box terminal will be required. Machined and polished distributor body can be painted with "cast aluminum" paint to provide a more OEM look if desired. Vacuum advance is adjustable using a 3/32-inch Allen wrench inserted through the vacuum hose port (not included). MSD Street Fire ignition does not ship with but are recommended.
