I am considering purchasing a 292 to rebuild. Complete from top to bottom including Manifolds and 4 BBL Teapot. Was a rebuilt at some point with a Tag on it. Been stored inside for Years. Turns over freely. Is there anything I can look for before purchasing? $500 CDN. I can sell some parts I don't need like Manifolds, Carb, and Distributor etc and get some Money back.Thanks
