I'm going to guess its a float bowl lever?












Maybe a photo might aid me more


My second guess is universal 600cfm vacuum secondary carb.

Thanx jmlcolorado, I'm building a another motor 383 and and was looking through the goods and remembered this one. ?? but I cant find anything about it on the web size wise...

Generally, the single inlet ones like you pictured are 600 cfms........not always, but most times. Those were used on a lot of production cars from the 60's. I had the same carb on a 289 Ford I swapped into my Austin Healy Sprite, and it was a 600 cfm. They are not as desirable as the dual inlet versions you see a lot these days.

Don't hold me to that though.

Here is a current version of that same carb.

1850's are 600 cfm vac. sec. i have about 10 of them going from 1850 to 1850-2

600 CFM like the guys said. For future reference, here's a list (22 pages ) of Holley carb numbers including model, CFM and common replacement parts.

Thanx Doc, yeah I'll have to keep looking with the 383 I need at least a 750 ..

I think the 600's are pretty good carbs, easy to work on, lots of parts!
Would be borderline fo a 383, if it has good heads, and med. to large cam!!
IMO
