New member here looking for some expertise and an opinion. Attaching a picture of an engine stamp on a 1971 convertible claiming to be an LT-1. Does it appear to be authentic in your opinion. Thanks in advance! VIN 194671S113133

You probably need to clean the pad of any paint so the folks here can view it more clearly. Use some lacquer thinner or acetone on a rag...don't attempt to scratch off the paint. I'm no expert but I can tell you that the engine is coded as a Flint engine, January 25, 1971 LT1 and a 4-speed from a Corvette.

Ray, I don't consider myself a expert but to many digits don't seem to align. with the Suffix , cannot tell on the VIN. the pad should not have any paint and really cannot see the broaching marks, or the VIN clearly.

Re: 1971 engine stamp

As others stated need to clean the pad and a clear photo of the VIN but based on just the Suffix code. My thinking is "Run Forrest Run"

Re: 1971 engine stamp

I've seen many stampings through the years with this one appearing to be suspect......not typical of factory stamping. Clean the pad, we'll be able to learn more.

This was hand-stamped with individual dies. No way were any factory 1971's done that way.

It would be nice to see the pad surface free of paint. Incorrect broach marks will be further evidence it's a re-stamp but we really already know that. If it has correct broach marks, that would not mean anything, either. If the block was originally a bare block or short block sold in SERVICE, it would usually not have any pad stampings but would have correct broach marks.
