I have always loved these motors. I search the list every once and a while but they are few and far between. The other night I happened on an add saying "New on factory create". I called, drove and bought. It was a 76 year old man who told me he had purchased the motor in 1964 brand new for a corvair project. Of course I don't believe everything I hear but with no tools and only my eyes and fingers I bought the motor on the "factory" skid carb to pan. He told me he had never ran the motor and it's literately sat since 64 in his garage. Everything appeared to be so. After getting the engine home and digging further all this seems to hold true. I've pulled the plugs and valve cover. It's brand new. Under the dist cap, brand new. In the carb, brand new. No evidence of ever being run. I'm half tempted to pull the rocker assembly and see if there are any marks on the valve tips or rockers. If this motor is in fact a brand new NOS 1963 Buick 215 well I sure don't want to be the one to run it. I was gonna turn it over until I noticed the TDC marks lined up. I don't want to touch it. Blow off the rat turds and maybe get it to someone or place that will display it or something. This thing needs to live on in it's "new" form. What say you guys? Are there any Buick guys or retired guys that can shed some light on this? Did they put these plastic caps on back then from the factory?
