Ran, that carburetor is for a pre '68 . It is not a monojet. The carb number you need was on an aluminum tag attached to one of the top screws. Most of those carbs were enough the same that you can get a carb kit for a mid-60s 250 or 292 pickup. The kits are universal enough that should work. Without the tag I don't think there is any way to positively identify what it came off of. Actually now that I think about it is probably off a car with a 230 or 250. The reason I say that is because it has an automatic choke. All the trucks including pickups used a manual choke with maybe the exception of the '67s. But I think even they did. I think the first 6 cylinder automatic choke was on the '68 monojets. Hope this helps. Joe
