Gettin off subject here but I passed on a 51 Lincoln w/suicide doors recently. Didn't know it had a 336 ci motor. (truck motor?) Had original auto tranny too but had been sitting outside with the widows down too long. The guy that built that flathead bike was talking about having to order a batch of 1000 crank bearings or rod bearings for that engine because they were custom order. (magazine article) Those engines hard to get parts for? Heads?
