He drag raced it at Minnesota Dragways in '69-70 and then pulled the engine to "freshen" it. He claims it has 13.5-1 compression. I told him we could pull it down and change the pistons to something more crap gas friendly and put it back in the car. He was going to sell it and buy a different engine but is thinking he may change the pistons now. Don't remember if it is Kinsler or Hilborn, but it is old school mechanical injection.
