The "1" designation generally survived here with the 51, indicating Ford as distinguished from Merc models and parts...then in '47-8 and on into the early '50's the parts prfixes went nuts for a while."


In other words, a "factory" REPLACEMENT block for '38-'42 24-stud, 221 cu. in. engines. DD

I'll win the lottery tonight, too.
