Overview
MSD machines this Oldsmobile distributor housing from billet aluminum using the same techniques as the rest of its line. Two sealed ball bearings guide the shaft, and a high-output magnetic pickup bolted to the base triggers the ignition.
The advance assembly is welded to a polished steel shaft and can be adjusted, and the cap and race rotor are supplied. The warranty is brief, and the listing names no ignition box requirement.
Who it's for
Matched to Oldsmobile builds that spin to high rpm and need stable timing. Owners with other engine families, or those wanting a longer warranty, should look elsewhere.
Pros and cons

Performance notes
Two sealed ball bearings guide the shaft accurately at high rpm, and the high-output magnetic pickup produces a precise trigger signal. The adjustable mechanical advance assembly is welded on top of the polished steel shaft, so timing curve changes are made at that assembly.
