Truck is up and running this morning, did a 12 mile drive so far with no problem. Based on the comments so far, my working theory is that the tach signal wire must have shorted to ground yesterday. Still have to trace the wire to verify, but very glad the HEI internals aren't fried which was my initial fear. Thanks to you all for the great feedback and advice!
