Klhansen,
The 7-10 mpg increase sounded bogus to me but I don't know enough about carburetors to call it. So I thought I would ask.

Jerry,
Thanks for the details.

As I understand it, from what I have read in th forum. A one barel carburetor either a Carter or Rochester is the way to go on a stock 235 for daily driving. Or am I missing something?

Also didn't the 261 come with a larger venturi Rochester? If so how would it compare to the 55-57 larger venturi Holley?
