How about trying to start it in neutral?? The neutral safety switch may be keeping it from cranking over, or it may be plugged into the wrong terminal on the relay!! It would not effect the lights and such, that sounds like a no ground or fusible link gone bad!! Damn I wish I was closer to come by and help!!
Memike offered his 170ci slant 6 on page 3, how close are you to Jonesboro, AR?? He is about 50 miles from Memphis so he must be at the top of the state! His was a good running combo only pulled for a V8 swap!!
