I have a 1956 Gmc 630 that has a rusted up 503 engine in it. Using scope to look in cyc's it has what I would call heavy rusting, have not opened motor up. Does any one know of any 503's still out there to be bought, or if any rebuild parts are still around, not even sure it could take a rebuild. Any info would be great.
