The ones on the left are newer style…possibly for a 230 or 250 engine. This type used an air cleaner with a central screw. The ones on the right are the old style model B…for 216 or 235 most likely.

1st design with smaller air horn / clamp on air cleaner, thru 1959.

2nd design on the left has larger air horn / center stud air cleaner attachment. 2nd design used from 1960 - 1967, replaced. In '68 by mono jet.

That choke/throttle cable bracket on the carb on the right is worth more then the carb itself. Don't let it get away.

It’s worth more than all 4 of them together.

Are you guys serious about the bracket?
It is that a running joke
Because I’ve never seen a shortage of them up in Canada
Every old carb has one

Good carburetion is fuelish hot air
The most expensive carburetor is the wrong one you attempt to modify.

It may be somewhat of an exaggeration but they are scarce & worth some $$ here in the States.
