Yenko aluminum block

<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: bergy</div><div class="ubbcode-body">This old thread was linked on another site recently &amp; it really brought back memories. We made the cores for these blocks at the Chevrolet Tonawanda Foundry &amp; sent the pattern equipment over to Lockport for aluminum casting. Then the blocks came back to Tonawanda for machining on a special CNC machine that was located up by the doors leading to the main offices. The machine was very advanced at that time &amp; the tolerances were much closer then the regular production equipment. The whole operation had to be quarantined because the aluminum machining chips couldn't get into the regular production chips (aluminum causes pin holes to occur in cast iron). I realize that the ZL-1 option was very expensice, but these blocks cost Chevrolet a fortune to produce! Also, theft was a problem - another whole story! My recollection is that the CNC machine was still in place at least through 1978. </div></div>

Bergy, did Yenko end up whith thise LC Blocks later or was it sold over the counter?
