First it's so hard from a picture so take that into consideration. Crooked JE looks like artificial aging And the beach Mark's don't look consistently parallel to the crank

John....I dont care for the stamp either. As NCRS would say not typical.

Is it possible to get a pic from as straight on as possible? I'm wondering if the gang stamped numerals are aligned but stamped at an angle relative to the pad.

When I get the car home this weekend I will clean the pad and take better pictures.

Nice Original..
 

Here's a nice original to compare take notice correct stamping and very visible broach marks!

Every plant has its own stamps so to compare a Nova stamp to a Corvette stamp doesnt matter. The same plants could have changed through out the year, so comparing to yours would be of no value

The Tonawanda assembly & application stamping should consistent in that time period/date!

On Corvettes I believe they had a separate gang set up for each build code. A Tonnawanda built 390, 400, and 435 built on the same day could have different type numbers. For example I collect 390 horse stamps built on May 3rd, 1967 (T0503IL) because I have a car with an unusual stamp from that day. A T0503JE or T0503JC stamp may use slightly different 0's, 3's or 5's.

Went and got the car yesterday cleaned the pad. The stamp looks much better the E is not crooked the camera shot makes it look crooked. The car has its original drive train

John,

Congrats! I am sure you will have lots of enjoyment with your new '67 Vette.
You have come a long way from "Mother`s Worry" :)
I look forward to seeing your Corvette.

Dan
