Catching back up ... If there is no serial number stamped into the boss aft of the distributor (like mine), then that means it's probably a crate motor -- built as a replacement engine. Mine was built in '59 but out of the '54 mold -- to be sold as a replacement engine for someone with a '54 or '55 1st series who needed a new engine.
Kevin -- My engine paint is Detroit Diesel Alpine Green -- left over from my 6-71 days...
Not meant to be a correct color -- just what I had at the time. Besides, it sounds cool to say it's a 2-61 ...
