3921968 is the exact casting # on my engine, thats how i found this forum!
i was serching online to find out what year engine i had in my 63 biscayne because i needed a crank pulley and every auto parts i went to said that they could not get it and that i would have to go to a junk yard!
so i typed in my casting # in a search engine and found this forum!
and i also found out that my engine was a 64-67? but i know 64 for shure. i was able to get the pulley the next day!
lucky for me the guy that i bought it from replaced the motor!
