Re: Yenko Aluminum 427?
 

The two Can Am blocks (sleeved 356 alloy and unsleeved 390 alloy..Reynolds) are listed in the 1972 Chevrolet Green Book (high perf manual), along with the 052 ZL-1.
Reynolds was a sponsor of McLaren, but as to where the 390 alloy blocks were actually made, would love to know.

Yenko obviously bought the tools. But who actually produced the Yenko-blocks, I don´t know. https://www.yenko.net/ubbthreads/imag...lins/dunno.gif

Blocks with Triangle - Frontier - Niagara Falls, NY
Hope this helps!

My friend Hans has the snowflake on his Yenko-block with the crest. Does anyone have a picture of a block with a triangle ? I´ve never seen one.

More cool Yenko ZL-1 info from Anders, via the Winter '86 issue of "Chevrolet High Performance"...

Re: Yenko Aluminum 427?
 

In the 1985 Chevrolet, Hot Rod automotive series volume 3 number 2, I found an article by Dave Riolo.
Quote: "...relatively few were originally manufactured by Yenko Speed and Marine.(Hopefully supplies will increase in the near future, if and when the company fulfills a recent promise to resume production of the famous Yenko aluminum V8.)"

I wonder how my friend Hans got his ? https://www.yenko.net/ubbthreads/imag...ns/naughty.gif
