Getting rid of learn burn.

If like my 1982 Aries 4 cyl, your distributor has a 3-wire Hall-effect pickup and no mechanical or vacuum advance, which was done in the "Spark Computer" or lean-burn box. You should be able to install a 1970's e-distrbutor. Its VR 2-wire pickup can trigger a GM 8-wire HEI module and coil for 1985-95 GM V-8 trucks. Many posts. TrailBeast here use to kitted parts.
