A little back story........
1970 Plymouth Roadrunner 383/TF
I got the car in 1999 to drive to high school. In 2000 the number 7 rod bearing spun. At the time I did not have the knowhow to rebuild it myself. We pulled the engine and brought it to a reputable local builder. It had to be punched 60 over and the crank turned. He had it for over a year before I got it back. By this time my mind had started to wander and I got the car running again and parked it in my dads shop. Over the past 20 years, I have had it running a few times, but nothing more. Always sounded great.
Fast forward to now. I have finally settled down and have dove into it. I just got finished putting electronic ignition, along with a new edelbrock 600cfm. I changed the oil and got it running decent. While idling, it developed a bad belt squeal. The alternator alignment has always been a little off, so this was no surprise. I figured I’d just pull the alternator belt and see about fixing the alignment later.
Squeal is still there. I then pulled the PS belt. Still there.......no belts on the engine at this point. A sharp constant screeching coming from up around the balancer. Spun main?
