Yes you are right. I need a full day to go thru everything. I finally found the guy who built the motor and talked to him. He told me that the motor came out of a 67 chevelle ss. He said it was a 327/360hp? I think he is full of crap. They didn't offer the 327/360 that year. He also said it was the High compression motor. Im basically where I was before I talked to him. Not really sure what I trust. He did say that the motor had less than 1000 miles on it when my dad got it from him. I would suspect the motor has about 15K on it if thats true. I also learned that the rear is a chevy...not a 9". he told me I can back up about 10" and it would hook possi. Never heard that before either. When I put the MSD in it I will go thru the things you recommended.
