From what I can see of it, I think the engine stampings are OK. The stamping above them is almost certainly the stamping of a shop that rebuilt the engine at some point in the car's history.

Re: Opinion on Engine stamp

I usually don't comment on these, but I'm going to go out on a limb here and say it appears NTFP.

Hey Michael thanks for the response but I don't know what that means NTFP

Hey Michael thanks for the response but I don't know what that means NTFP

Standard NCRS acronym for "Not Typical Factory Production". Which in judging would garner a deduction of points.

Re: Opinion on Engine stamp

You're welcome. Not being a mechanical judge (the ones who judge stamp pads, among other things) I don't know how much deduction it would be. As Joe says, most of the pad appears fine, but it is surprising a rebuilder would do such a thing to a valuable area like the stamp pad of a Corvette. Must have been done long ago when these were just another used car.

Re: Opinion on Engine stamp

Raymond ---- I agree with Joe. The VIN and Flint stamps look completely original, and the grain is also good. The Cummings part is certainly a shop that rebuilt the engine before anyone cared about stamping pads. At least they left the GM stamping alone which is better than most rebuilders who would have decked it even if it wasn't necessary.

Re: Opinion on Engine stamp

Raymond,

Welcome to the Forum.

The engine casting number, casting date, plant assembly stamping/partial VIN, and engine pad factory machining marks are all judged by Standard Deduction Guideline #1 found on page 29 of the current Judging Reference Manual. I don't see where any points would be deducted using SDG presuming the casting number/date/assembly date/VIN are also appropriate for your car.

The JRM is available (inexpensive) from the NCRS bookstore.

Re: Opinion on Engine stamp

I agree with David H in that NO points should be deducted. The rules for the pad surface do not require that the entire surface be 'original' just that some traces remain.

I would tend to disagree. I do not believe any of the judging rules specify "entire"; it would be naturally presumed anything additional is NTFP. Applying a standard of the word "entire" being absent from the judging standard would allow all kinds of addition modifications, such as pin striping, racing stripes, etc

Philip,

There is no NTFP provision for judging engine cases, only the Standard Deduction Guideline #1. Matrix judging (CDCIF) only comes into play when there is no Standard Deduction Guideline for an area.
