This is our most popular performance distributor! The housing is machined from a billet of 6061-T6 aluminum on a state-of-the-art CNC machine producing exact tolerances. For high rpm stability, a .500” steel shaft is supported by a sealed ball bearing and a long sintered bushing. This shaft also receives a QPQ coating for friction reduction and resistance to corrosion. A precision machined reluctor is attached to the shaft which triggers the magnetic pick-up mounted in the housing. This high output magnetic pick-up is the most accurate way to trigger your ignition. Plus, with no moving parts to wear or adjust, the pick-up is maintenancefree! Just above the pick-up is MSD’s adjustable mechanical advance assembly. Different springs and stop bushings are supplied so you can tune an advance curve to match your application.

By Anonymous We will never use any product other than MSD in our 900 hp small block chevy racing engines. Our experiance has shown that those with problems with their MSD products, 9 times out of 10 have not installed the ignition correctly, or are to quick to blame the ignition system. |

By Anonymous highly dissapointed in this product. Car has been garage kept for 5 years now after complete rebuild. All new MSD ignition was purchased and installed in my camaro. Today the car died and would not restart. after a brief diagnosise I removed the cap and the entire internals of the dizzy were completly rusted out and the distributor now has a broken shaft. I am very disapointed in the material used in the production of this product. And the bad part about the whole thing was that I had only put about 300 miles on the car since the rebuild. Poor product and I am not very happy with MSD anyways. |
