Which FSZE engine is this?

Have you ever seen a fsze engine with a metal resonance chamber?
The block is stamped fs9, looks to be a fsze

lol disregard my post.

Do a search and you will see what i mean. Blocks may be stamped based on capacity im not sure but either way standard FS blocks are stamped FS9.

Well probably all fs blocks are fs9? not sure... but what is with the metal resonance chamber?

I know but it makes one wonder bout the difference, between the plastic and metal resonance chamber
