That '67 Corvette was built on February 13, 1967; the engine build date is October 13th, 1966, and the suffix indicates an L-71 (427/435hp) with K-19. I'm not comfortable with an engine sitting around at St. Louis for four months before going in a car; it'd be a stretch to call that anywhere near a normal time span. What's the casting number and date?

[TXZS]

John, the casting number is 3904351 and the casting date is "I76". What do you think? Tex Timberlake

The casting date-to-engine assembly date is kosher, and the casting date-to-car assembly date falls within the 6-month NCRS window for full judging credit; probably OK, just not "typical" (but that's why NCRS allows six months - inventory control was pitiful in those days).

Fyi; the NCRS; (NATIONAL CORVETTE RESTORATION SOCIETY) will accept up to a 6 month spread from engine build to chassis installation.
