Any idea what carbs these are by looking at them just from picture? From 260Z but not sure if they are originals

They look like stock 73-74 flat tops. Many people will tell you to change them to round tops. I say, if they work, leave them on. It's not that hard to clean them up and get them operational. I've had success with them 'back in the day'.

Stephen gave you good advice.

1973 240Z flat tops were Hitachi HMB46W-1 or HMB46W1 depending on what you're reading. I dont know if the 260Z carbs were exactly the same model or not. I'd bet they were very similar if not the same.

Have fun with your project.

Yup, sure look like the Hitachi's to me.

Just looking at the picture, everything looks original. I have a '74' 260

I thought all 260Z's cam with stock dual down draft webers?

No (us anyway) came with down draft webers carbs. They were aftermarket only. After the flattopps came FI.
