Carter Carbs

Anyone know which carbs match up to the Offy 3x1 manifold for the 216 Chevy? I'm guessing those Carter W-1s will fit, but will this Pontiac carb fit (item no. 2469836719)?

The Rochesters work real nice, I don't know the mdl # but they are the ones that came on the 235's in trucks and cars in the mid fifties.

HillBilly.....I have a new one for my 41 Pontiac 6 banger. Should be the same as that 49-51 I can measure it between the bolt holes if ya want.

 

I got a bunch of the 1bbl rochesters for the 235 engine let em know if you need them. I also got some W-1's as well.
