So much for the " it came out of a running, driving car. Drop it in and go."

Oh yes! I see! Rebuilt 20 years ago and has low miles (for a slanty....) and it was good when we pulled it for a V8. (Even though we pulled 9 years ago...)
It has seen regular Maintenance. (Twice a year oil change, needed or not...) Driven by this dude’s wife (Ex drag racer called “Lead Foot Ma’ma” 5 time local street drag champ, even has a Walley or 2....) and her daughter for a few years (the daughter who also drag raced the car and try auto crossing it as well...) and rarely driven by the guys son (because he grenaded the rear followed by the trans 50 miles later after the new rear went in..) but it was always good to us going out to picnics and donuts (kids taking it keg parties and empty parking lots for all night era drinks king and doing, well, parking lot donuts!) I’m most SURE this will serve you well (after you spend 8K) in your car.
