YZ is for an auto trans.

That is a 1970 4 bbl intake. Used on all 4 bbl engines except the RA IV engines. The 9794284 should be 9794234, the '8' is probably being misread. It is also a 4bbl intake used on all the V8 engines in 1969 except RA IV engines.

I'm located in West Tennessee, I have not had the Block inspected, it came with a project car I bought years ago and has been in dry storage ever since. As AG pointed out YZ is for an automatic car. If you are sure you want a YZ block with a late 1966 cast date I can look into getting the block inspected and then we can discuss price. I also have several intakes and a set of 670 heads that have been rebuilt with hardened seats installed
