Built it and never got to use it? It must have sat for decades. I would be afraid to go through all the work and fabrication to make it fit and work without hearing it run first. You may have to rebuild it to make it run and not use oil and leak all over. The headers won't work. No one makes headers for a AMC in a Mopar. Do yourself a favor and swap a Mopar small block. Parts are made for you.
