This past January, I bought a '69 Yenko Tribute car with an L72 427/425 engine.

It is stamped T0512MN, casting number of 3963512, and I can't make out the entire VIN 9N6xx308.

I am somewhat of a Camaro rookie (although I have owned 4 of them, 2 currently), how rare and collectible is this engine?

Because this was stamped with the MN code along with the casting number of 3963512, would this engine been solely used in COPO Camaros?

The car is awesome, and is a keeper.

Hi Matt,
Nice looking car! it's very possible the engine stamp is also a "tribute", if you can post some clear hi-res pictures, the knowledgable guys here will be able to comment on originality and value :thumbsup:

Like Tim said, post excellent pictures of the stampings and the experts here will tell you if they are original stamps or restamps. If the partial VIN stamp is on the pad, it is probably a restamp. By the time they were building VINs in the 6###### range, they were stamping the partial VINs down by the oil filter. Does the partial VIN match the VIN of your car?

No, the VIN doesn't match the car, but it knew that before I bought it. The guy that I bought the car from told me that this engine and transmission (M21) were purchased by a collector in Utah. I was not given the name of the collector.

The VIN was near the oil filter. Here is the best pic that I have right now.

I will send other pics shortly.

Thanks guys.

I know what you mean, Matt. A couple years ago a thread like this would've exploded with posts. Since the concensus is the stamps are real, you'd think it would've generated a bigger buzz. Congrats on having a "real" engine! :hurray:

This is kind of a total reversal. A real engine with a cloned car around it. Still it looks really nice and to know it has the COPO block is a big plus.
Back in the day we did "Rebody" restorations, and nobody thought anything of it. You could not get the aftermarket parts so you just got a good donor body and put in the running gear. One of the caveats was that you had to scrap the original body and get the DMV to sign off on the new one. But that was just a formality. Now it is a different story.

Yes, it is a little different then what you normally see. The guy who did this restoration did it pretty close to Yenko specs; M21 trans, 12 bolt posi, 4.10 gear, cowl hood, 4-core radiator, high performance suspension, SW gauges, AM radio, 140 mph speedo, body is straight and clean.

I added the Torq Thrust wheels and will be adding a SW tach on the steering column.

This car is a keeper, especially now that I know the engine is a real COPO block.
