A much sharper photo would be helpful.

It appears your vin is 38508. Very late car made December 69. 38762 was the last 69 car. The engine code T 1202LR fits Dec., 2, 1969 ''LR'' 427/435hp. Differential date should be close.

What about authenticity of the stamping?

Joseph,
The heads have definitely been removed and replaced. Are you aware of any engine work done to it?

Re: Engine pad stamping; I think it looks correct, but what do I know?

I guess I’m looking for a little piece of mind here since I’m starting to invest some real time and money above my initial purchase price.
Im fairly certain I’ve bought a real deal L71, but with no documentation and the ability to restamp an engine pad, who knows?
I recently registered the car, and the agent noticed the mileage on the sellers pink slip (42,xxx) didn’t match the mileage on the dash odometer (14,xxx). Seller had no explanation for this.
So obviously since this I‘ve had this slight nagging doubt.
I though I would post a picture and get some opinions.
This 1969 has the correct 6500 redline, the 15/16” sway bar, correct numbers matching HD rear end and the seller said it had a single fuel line.

Also, The seller said it was not a numbers matching transmission and I confirmed this.
I noticed it’s a M21 and not a M22. For some reason, I assumed that these higher HP cars would have the rock crusher 4 speed and maybe it did originally but during its street racing career perhaps it blew up and was replaced with the M21.

For 1969 the M-22 transmission was available only with L-88 or ZL-1.

Yes, the motor, trans and rear have all been rebuilt when the PO started the frame off restoration almost 25 years ago.
the car has never been run since.

Thank you Joe.
WhT is your opinion of the stamping?
Original or not?
thank you in advance…

To be honest, it does not look quite right to me. However, I really have no expertise in evaluating stampings. Al Grenning is the guy to consult on this and it's worth paying him to evaluate it prior to a purchase. Post-purchase, it's academic but it still might be worth it to an owner.

Re: Engine pad stamping; I think it looks correct, but what do I know?

A couple other clues to look for are does it have transistor ignition with original wire harness? All L-71s had it. Check your front springs for a green EA sticker which indicates F41 suspension. If it has that it's a L-71 for sure. Only 3 models in 69 could get F41, L88 and ZL1 ( which your car is not) were standard with F-41 and L-71s had the option to get it and most did. If the stickers are gone you can check your rear shock mounts. If they are the bigger ones that's also a indicator of F41 but not definitive because they are easy to change. The green EA sticker on the front springs should be dull in color. The remakes are shiny.

What's the cast date and cast # of the block. Date should be any where from a few days to 2 months before assembly date. Cast number should be a 512 block.

Block casting date is 3963512
So according to my pocket NCRS reference book is correct; late 69 427

Re: Engine pad stamping; I think it looks correct, but what do I know?

3963512 is the block casting number and that is correct for L71. The casting date will be a different number like H 12 9 (August 12 69 ). That date should be before your engine build date which should be before the car assembly date. That number is in the same area as the block casting number.
