Carburetor Question

[Jake65]

Will a Rochester One-barrel carb off of a 1954 chevy, with supposedly a 261 I-6, match the same size carb off a 1965 Chevy with a 292 I-6? If they do match would they work together running the two carbs together?

Moved ya to engine and drivetrain for more help.

If it really came off a 261 and it's the original, it may work. Keep in mind that these carbs were engineered for every conceivable configuration so I would get all the info off the carb and do some searching. If the cfm's and jetting are close, I'd give them a try.

btw: I've read the 261 if pretty rare engine. I'd like to come across one of these and put it in my 68.

They usually have larger venturi,s then the 235 carbs. You can look at them from the bottom & see the difference. The air cleaner mountings are going to be different on the 54 & 65. I don't think 2 of them would work good for a dual setup. It probably wouldn't idle good at all. You would be better off with 235 carbs or even 216. The 216 have smaller mounting centers though.

Yeah, the 3 carb setup is a better alternative. Check Langdon's or Clifford's sites.
