1969 Chevy Nova HEI Ignition System - Spark It Up
|
As should be done whenever any of the ignition components are serviced, we picked up a new cap and rotor set before proceeding with the 6AL conversion. The kit comes with two contact buttons. The factory-style button has high resistance to limit electromagnetic interference or radio noise, but can actually heat up and melt the cap when used with a higher-output ignition like an MSD 7 Series. The lower-resistance button helps keep temperatures down, and a good set of wires will keep EMI in check. We used the low-resistance piece, and then installed the required rubber washer before clipping on the modified dustcover. Note the long contact piece in the new dustcover; this works as an extension between the rotor and the secondary coil tower on the top of the cover. View Related Article
