Well, my roommate went a different direction on his Z. After purchasing these carbs, I rebuilt them with kits from Pierce manifold. They're beautiful carbs, and the whole kit would be a wonderful addition to someone's Z build.

He's looking to get $1200 for everything, which includes filters, velocity stacks, electric fuel pump, and possibly some other assorted things. They are real vintage Bologna Italy webers. I also rebushed the linkage and everything seems in super shape. I'm unaware of the jetting, but I can check for someone's whose interested.
