Matching Engine Numbers???
I have a 427/425 1966 convertible SN 194676S124735. On the passenger front engine are the numbers T060IP 6124.735. Also casting 33869942 date code E206. Do I have matching numbers or could they be forged?
Engine Assembly number actually T0608IP 6124735

Can you post a clear photo of the stamped pad to see? That's about the only way anyone can venture an educated or experienced opinion.

You have already answered your own question......yes, the numbers match, forged or not. Thats the problem with using terms like that. Now if you wanted to know if you had the ORIGINAL engine, you could start by posting photos of the pad and casting numbers.

Your dates line up. Your VIN suggests an early June '66 and the assembly date is 6-01. The engine casting date is May 20, thats good. Good start.
As the others said, get a nice closeup of the pad posted here for some more scrutiny.

What you have posted is not complete engine stamp. There is no day in June "0" so I would assume you left out a number??? Perhaps the pad says TO601IP? Or TO605IP? The reason I asked is others have pointed out dates line up but, but we don't really know what the engine build date is for your car as yet. IP is an L72 suffix (427/425), so again, I assume your engine is a June 0..something... IP car. PHOTO is what is needed here for further discussion

It's not possible to evaluate a stamp pad that's been painted; use some paint stripper or lacquer thinner and remove the paint, and don't use any kind of scraper or abrasive material.
The closer you can get and the highest resolution, the better; make sure you use the "macro" function (the little flower symbol) so you get good focus.

In case your wondering why do they want the paint removed, it's to see the pattern or grain behind stampings. In addition to letter/numerical arrangement, spacing, and proper characters If you pass this test, final will be a breeze!
But it is extremely essential (as previous blogger stated) not to use ANY abrasives. I prefer aircraft stripper apply heavy (out of the sun, keep moist), acid brush works very well, hour later wipe with paper towel = great results.

That looks pretty good to me. Now someone who really studies these things will probably weight in and prove me wrong and say it's a re-stamp. Hope I haven't jinked it.

detrana - It appears from what I can see to be correct, however have slight problem with pad lines or (machining lines), requires a closer look as they appear to be slightly skewed, could be camera angle. With that stated, I would ask for another opinion to be certain as I don't view many C2 pads (Tonawanda), as I am a C1 (Flint) enthusiast.
Wish you well, rustylugnuts

I don't see a problem with that pad from an appearance standpoint

nice pad with assembly date that appears correct for car number 24735. assembly date has correct broach marks, while the 6124737 appears to have lines that could very well been made by lined paper that has been lightly tapped with a hammer. it also appears that the area around the 6124737 has a different shade than the assembly date area. this usually occurs when a area has been filed down. i would put a straight edge across the whole pad and see if you are lower in the 6124737 area. if there is not a noticeable dip i doubt that anyone can disprove that the pad is original.
