Thanks for the replies, fellas. Joker, it ran like a top before I put the heads and intake on, they were just from a smogger 305, so I replaced them w/ 1.94 valve double hump heads and a weiand dual-plane intake. Hotrod, the ignition switch was off, but the battery was still hooked up. I'm gonna check the wiring from the Ignitor II module again to make sure its not worn through; this one has me puzzled.
