Clarity of the photo is not adequate to determine broaching authenticity. Partial VIN from what I can detect is not correct. "7" should be an alpha character for the plant that the car was assembled ad there should be 2 more numbers preceding this. [/ QUOTE ] Dana - Corvette you say?

Re: Block Stamp
If that CON VIN configuration is correct for a Corvette, then one would assume this is supposed to be a 67 427/435. The stampings look good to me, but have to agree with Sam that a clearer picture is necessary to get a good look at the machined surface.

Re: Block Stamp
Yes Sam, there is something besides steel out there. Once you have had a midyear it is hard to get it out of your blood, especially a big block. That glass does itch though when you sand it. I like steel too.

Re: Block Stamp
The picture is not clear enough to see a broach. I compared to other '67 Corvettes in my picture library and I think the stamps look good. I'm comfortable with the "7" in the VIN and it should have only seven digits in the vin.

Re: Block Stamp
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?

Re: Block Stamp
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).
