I have a complete running olds 455 engine for sale, its low millage, I don't believe it has ever been out of the car or into, I purchased the car from the original owners. I would say it needs the basic gaskets and tune-up because it has been setting for years. Will come complete carb to oil pan, the ac even blew cold for a bit. I think it's a 73 model but will double check. Still in the car and I can send video of it running, located just south of Nashville tn, thanks $800
