Need information on rebuilding A Engine

[50Trucking]

Recently purchased a 28 Tudor that had been setting for 25 years. I rebuilt the carburetor, distributor, belts etc and it cranked and ran fine. It burns no oil, does not smoke or run hot. I took it on a 50 mile trip and it started knocking. I live near St. Augustine Florida. I need information on sourcing parts for the rebuild and where to get the rods and block re-babbitted or inserts put in. Possibly someone to do the complete build.
