3916321 for early cars; 3935439 for late. The NCRS will accept a block up to six months prior to your 68's time/build date. Closer is better. The smallblock in my 68 was cast at the beginning of April, assembled on April 9th, and the time build code is April 20th.

#7690 would have been assembled in December, 1967.

Good luck with the hunt.
