It will never be correct with the wrong VIN on it. There is nothing "acceptable" about dates that "could have" been appropriate unless the VIN is going to be restamped.

Note: if the original poster meant NCRS judging, we are talking about a different use of the terms "correct" "acceptable," etc.

My '69 BB got its trim tag on June 23, '69. Engine had been cast in early march, assembled end of March. There was a 6-week strike (May?) that year, so this is a larger gap than is "typical".

Also, NCRS considers parts "correct" if produced within 6 months prior to build date.

If you are going for NCRS points, you can use the "010" block in a late (august 69) 69 model year production Vette. You want the casting date to be before your car was built (within 6 months).

1969 had 3 or 4 different casting numbers used depending on when the engine/car was built. "010" was the last casting they used in 1969. If you have one in your car, you will get most all of the points available for the cylinder case.

If the VIN stamp marches the car and the assembly stamp matches the application, you can get just a few more points.

Mark is correct... I assumed the deductions would be higher.

casting # and configuration -350 and no further judging of items below
casting date -175 and no further judging of items below
***'y stamp -25 only
VIN derivative -25 only
pad finish -38 only

Your car was probably not involved in the strike. If you're wanting to get as close as possible, stay within the three weeks prior to your time/build date. Two weeks prior would be better.

Example: your car has a time/build date of August 15th. An engine with an assembly date of the last week of July or (better) the first week of August would work.

Engines were assembled and shipped to St. Louis before the cars were built. An engine assembled the week your car was built would be cutting it too close and would not allow for shipping from Flint/Tonawanda.

Halfmoontrail,
That is VERY similar to my 69 BB car's dates. Trim tag June 11, Casting date in March, Engine built March 25. I tend to agree with the strike theory, and we have two examples.

I've generally heard six months prior to build is the "acceptable" range for a correct dated block.
