Thanks for the details fellas. I have an old 228 that I was trying to id. Turns out the data plate is missing the the flat spot behind the distributor has been ground down or never marked. The cylinder head casting number is 6107412 date code L198. Block casting number is 6107326 and date is j256. Im wanting to buy a maintenence manual as a rebuilding guide and was wondering if I should buy an earlier or later manual since there might be mechanical differences.
