I have a 3919850 intake but the numbers are stamped on a rectangular pad where the casting number would normally be. My thinking is this was cast in one of their early molds before they had assigned the casting number. The date on the bottom is 12/18/67. I've had the intake for 10+ years.

Will this pass NCRS judging?

You should post it on the NCRS forum for that answer.
