MSD Pro-Billet distributors share the same CNC machining techniques as the rest of the MSD distributor line. They feature a housing that is machined from high-quality 6061-T6 aluminum for durability and show-quality looks. Their oversized shaft receives a QPQ coating for friction reduction and corrosion resistance, with the added strength of two sealed ball bearings that guide the shaft accurately at well over 10,000 rpm. An extra-long sintered bushing replaces the ball bearing at the bottom of Chevrolet models. TIG-welded on top of the polished steel shaft is MSD's accurate mechanical advance assembly. The weights are supported by nylon pads that allow the advance to operate smoothly throughout the rpm range. For all-out racing, the advance mechanism can also be easily locked out. To accurately trigger the ignition, a high-output magnetic pickup is bolted to the base. This pickup produces a precise trigger signal that will never vary more than one degree at any rpm. A durable gear is installed for performance applications, and an MSD red cap with brass terminals and race rotor is supplied. They're available in standard and small diameter models for applications with limited clearance, and require the use of a separate ignition box such as an MSD 6, 7, 8, or 10 Series ignition.

Perfect for my FRPP cam

This dizzy is already set up for the gear on my FRPP F303 cam, has great instructions for setup and complete spring/bushings to do so. Set it at 12deg for initial start, ran it for a while to start break in, ran it up to 3000rpm and set it all in with my spring/bushing combo and it makes my 351w sing. Lots of comments out there about failed pickup units, so I bought a spare, just in case. ...read more

Big improvement in operation!

Summit RacingSummit Racing Verified Purchase

I was unable to determine the reason that my old distributor did not provide full advance and Kelly engine was hot so I purchased this one. It installed easily and had all the required parts to adjust the timing to match the engine manufacturers recommendations. The car runs 100% better now.
