Hi everyone!
I have found an aluminium YENK0 427 block for sale and I have some questions about it.
How common are they?
Are they still produced?
What is the market price?

I have no casting # yet,but I will post them a.s.p.

Thanks for your help.

If it's an original Yenko block it ought to be worth some pretty good scratch. But what would be really sweet is if you could find the car with the matching VIN . . . there are some on this site that might be able to help with that. I'm pretty sure there is a national registry of some type with VIN #'s. Many of the current owner's frequent this site I believe.

Yes Jody has a Early Yenko block in his car. The most common Yenko block has the Yenko logo cast into the front of it. It is a neat piece but never came in a car. To price it you just need to compare it with new ZL1 blocks that you can buy today. The new blocks are supposed to be better so I would assume a 30 year old Yenko block would be worth less than a new GM block.

These blocks came in many flavors: water jacketed or non-water jacketed, screw in or press in freeze plugs, tall deck or short (I think). But, they are of the older casting, so they aren't as tough as the newer version (like stated above). In fact, a couple of the guys with the Yenko blocks I have talked to have filled them for this reason.

I have saw more with "YENKO" spelled out, rather than with the actual Yenko "crest", though. Ours has the "YENKO" lettering...but we would REALLY like one with a crest

There was also a Can Am block that was different then the ZL1 block. I inquired about one that was for sale a few years ago. The seller said he had a receipt from Yenko with the name of the purchaser written on it. The purchaser was a guy named A. J. Foyt. Anyone ever hear of him? I asked if I can buy a copy of the receipt and he said no.

If you are looking at stroking it and throwing some power at it, then that might not be a bad idea. The newer versions are a lot better built. But, the older block(s) would work, just not gonna be quite as strong, and might need to be at least half-filled if you really build it. But, just my opinion...
