I guess I should have said I wanted to keep it as stock as I can as it left the factory, lol. It originally came with a 235. After talking with the guy I bought it from, at one point the guy he got it from took the original engine out of it and put some kind of V8 in it. Sometime before it was parked in 1980 the V8 was removed and this 216 was put in it. I'm still trying to get the contact info of the guy who parked it at my parent's neighbors house 40 years ago so I can try and find out more about it's history.
