On my 1977 I once paid a hack shop to do a full tune up, problem was the distributor had to be re-indexed as it was all the way over to one side of the slot, and could not be turned/rotated anymore.
I had no low end power and it was running 30 degrees too hot on warm days.
Once I got it re-indexed (by myself and no thanks to that hack shop), I was able to get the ignition timing right. It ran cool and like a Porsche should after that.
