This ad says his 69 427 512 casting and an LE suffix code is a Yenko?
My NOM 69 427 512 Casting has an LE suffix and I looked it up as just a passenger car motor, not even a high horse engine. Am I missing something here or is this just another one of those ads?
I'm going to take a 'wild' hair guess on this one. :jester
Yenko was dealership that dealt with high perf. cars during the 60's.
There is "no" engine code designation for a Yenko.
However, there is a Copo code that designates a 427 in a Camaro which was used my Yenko, Berger, Nickey, and other dealerships.
The fact that your block has "LE" confirms the 427 iron block identity and nothing more......(except for how it was setup in a vette - carbs, etc.)
I could put control arms on eBay and say they're L-88 / ZL-1 etc. and technically nobody could disprove that......however, we here all know that a '68 vette control arm is no different than an '82 or a '69 ZL-1 or even a split-window '63....... ;)
"Yenko" is just a buzz word so that guy on eBay can get more bids.....that's all. Always be very, very :skep: ical about these things because Yenko, L-88's, Grand Sports (C2's)....and other Rarities are in fact just that..... RARE ...as in you shouldn't see 15 listings for the same darn thing in the same week on eBay ! :yesnod:

Absolutely correct...
The broadcast code for a COPO 9561 Camaro (427/425 L-72 engine) is "MN" for four speed manual transmission applications and "MO" for automatic equipped cars. With an "LE" code, this obviously isn't what it is claimed to be.
A bare block (standard) with one of those codes (applied at Tonawanda) usually bring $2,500-$3,000... They are rare AND desirable in the right circles.
So I was right in assuming that I have one of the RARE 2 bolt passenger car motors that came in thousands of cars in 69.
Mick,
While not a rare piece as it stands, it is a "512" block with a casting date of B 5 9 (February 5, 1969)... A date suitable for a 1969 vehicle built during the late first or second quarter of the 1969 calendar year. There are a few skillful people out there that can make it "correct" for any application that you might wish to use it for... From adding four bould main bearing caps to creating a different broadcast code/assembly date (with the correct broach marks on the pad).
That block is still worth $1,000-$1,500 to the right person.
