This car has been sitting for 3 or 4 years.The carburetor was not properly installed and a bolt came loose, the engine got too much air and backfired and pulled the stud out of the intake.The intake needs to be welded, retapped, or the intake replaced.

I have over $11k in the engine alone, selling it cheap because I’m making no guarantees on it.
