Raw Casting ZL1 Block on eBay
Is there any way the bids on this block could be real? Even if all the machining was done, wouldn't the block still not have cast in water passages? Jason |

I have records on many solid blocks that Yenko cast, typically for drag racers.A lot of that history is in my newest book.." The Yenko Era..

The cores in the cooling cavity of the block are usually made of silica sand,when the block is machined the sand exits from the frost plug and cooling holes.They usually go on a vibrating machine to loosen the particles of sand.Theres more to the process then i mentioned.

They show a picture of the part number on the back of the block. But there is no casting date on the driver side of the block. Another tall Ebay story? It could be true. But event preproduction parts have casting numbers and dates. I checked my pictures of the block I had to confirm my suspicion.

I too would believe the core still has sand in it. Isn't there a way to check to see if there are hollow cavities? Tapping would surely give some type of indication.
Were the Aluminum blocks broached or did they use a rotary cutter?

There is no water jacket core - if the core was there, it would have printed at the freeze plug. Aluminum blocks were milled (rotary cutter)

A couple dozen unmachined raw castings were shipped to Smitty at Yenko Performance and Marine in the early 80's. My records indicate that he thought some racers might want to do their own block prep.
