I have a 1973 Cadillac with a 500 cubic inch engine that has been sitting in a barn in Maine for 25 years. The valves are stuck. I can get it started, but it will shake violently and sputter out after a minute. I took the valve covers off and can see the valves are stuck. I pulled the rocker arms and have been squirting them with Marvel Mystery Oil. No luck so far.
I am looking for a guy who has worked with the older GM 500 and 472 engines from the 1970's and has experience with barn-find restorations.
It is also missing the rear window. I have the replacement glass, but I need a guy to help put that in as well.
