Re: ZL-1 aluminum 427
And does anyone know when Yenko first cast his block w/ the 'Yenko' in the casting....before or after GM made the Winters ones available? ~ Pete

Re: ZL-1 aluminum 427
I thought it was later too but think I read somewhere once that it was before? . Also last weeks posting of this months ZL1 feature car that has a 'Yenko' one in it sounds like he may have put it in soon after he got it when he set the orig motor aside? ~ Pete

Re: ZL-1 aluminum 427
I believe all ZL-1 were cast in 69, I dont know about Yenko. These blocks were sold thru 1973. Does your block have a Winters mark on the front, or a Yenko mark?

Re: ZL-1 aluminum 427
Where can I find some detailed information about Yenko/ZL-1.
I just bought a 68 Camaro with an all aluminum engine in it with Yenko cast into the block. It came with all the original Yenko receipts for the engine when it was bought new in 1978, but I would like to find out some more information if possible.
