Is this a ZZ4?
I am looking at a complete engine. Alloy angle plug late heads, casting number on the block is 14093638, stamped VO725ZZZ. Intake is a Winters foundry 14044836, and it has rams horn center outlet exhaust manifolds on it. Any thoughts?

I believe what you have there is the original ZZZ crate motor from about 5 years ago (maybe more). Want to say about 325 hp with a single pattern hydraulic flat tappet cam. From what I understand, the ZZ4 is more streetable and has more power.

Not sure about the one your looking at, but i have a zz4 with the HOTCAM, and it is streetable still even after i added the HOTCAM. So either way its a great motor like SteveG75 said!
