I too am curious about production amount. I have an aluminum 427, casting # 3940652, I cannot find a serial # but on the passenger side down low next to oil pan it has a # 66 stamped in it. what is the rareity and value?

Re: how many zl1 motors were made
 

Is there a cast date on the block? Is there a number below the cast date? Also look at the back of the block in line with the distributor there should be a number stamped there also.

For those that are interested in the new ZL-1 block here are some pics of mine right out of the crate. After taking it to the machine shop they have had a stream of people coming by to see it and commenting on it's high quality. I know I'm very happy with it. Not quite the nostalgia of the old one but a much better built and looking block.

Re: how many zl1 motors were made
 

Although helpful Les, Preve's listing above shows only F-body suffix ZL1 motors and doesn't appear to include the Vette ZL1's nor any supplied to McLaren and other Can-Am teams etc. . Isn't there something about 5 or 7 'Vette ZL1 motors being originally produced then some returned? . Can the Can-Am motors can be referred to as a ZLI since they're a different displacement? . Are all the Winters Alum. blocks the same casting number? . Perhaps the question could be....what other GM-Winters Alum. block motors were released to add to these known F-car engines resulting in what Grand Total? ~ Pete
