OEM Mopar Modified Distributor Reluctor Stops Misfires!
Gennie Mopar, modified to cure a common problem! Read on....

Smallblock, Big Block, and Hemi owners - listen up! If you've got either an OEM Mopar electronic distributor, or a MP aluminum distributor, here's a cure for that all-too-common, hard-to-diagnose, misfire problem! This can be intermittent, and cause you to drink (or, drink more, as the case may be.)

Frequently, due to a myriad of problems, your distributor rotor tip is NOT POSITIONED SQUARELY UNDER THE CAP LUG (terminal) when firing takes place! Result: an intermittent misfire that can drive you nuts; no amount of external fiddling can fix this. The cure is re-phasing the reluctor on the shaft, so that when the plug fires at, say, 35 degrees BTDC, the cap terminal is aligned with the rotor tip. This is accomplished by re-indexing the reluctor, which requires a reworked reluctor with additional locating slots. And E-berg's got one for you, CNC precision machined, complete with detailed instructions.
