Hi All,
New to the forum. So here is my initation question. The NCRS judging manual states that casting and or date coding up to 6 months previous to the car build date are acceptable. Actually in the new mid year judging manual I cannot find it at all but previous revisions stated 6 months. My question is, What is the norm? My 64 was built in June so for any component what would be a good target for casting and component date codes assuming no instances of that old part at the back of the shelf being used during production. My stable items such as radiator and expansion tank are May, but for other items that may have been replaced with no attention to date what would be a good target. 6 months to me seems a bit wide.
Thanks, Jeff

The NCRS Judging Manual has six months as an acceptable window, but that is not common. Most parts were much closer, more like two or three weeks and many less than one week.

As an example, on your car, I would expect to see engine block casting dates no earlier than May, with a build date a few days later. The intake casting date will normally fall close to the block date. Valve covers are not removed so head casting dates are not judged.

I suggest you look for parts that fall within the two or three weeks before the build date and only deviate from that as a last resort.

Thanks Verle. That being said then what should the aprox date gap be between the engine build and the car assembly date? A few days seems logical.
Thanks, Jeff

Jeff,

It is about the same thing, a few days to a "few" weeks. Less than two weeks is common.
