Thanks to everyone who responded to the last couple of posts. Like I mentioned before, I've got a 75 Scout II w/ a rebuilt 392. My latest issue is the ignition crapping out at random times. Sometimes it'll do it only when hot, sometimes stone cold in the driveway. Every time it does it, I check for spark and get nothing. Plenty of fuel and the engine turns over, but no spark at the coil. I'm looking at eliminating the stock gold box module, and going to Pertronix's in-distributor module. How do I tell which distributor I have? They make modules for Holley and Prestolite. The distributor has IH markings only. Any help would be appreciated.
