This seems to be a constant occurring and fretful subject regarding two carburetors on a 235/261. If one insists on making water run uphill and helping politicians be honest then your task is pretty much futile. Your dealing with a subject that is impossible. Unless extensive modifications have been made to both the top end and bottom end of the engine you are trying to make a mule into a triple crown winner. Pages and pages on The Stovebolt have been dedicated to this issue. It will NOT work! A good running model B or Holly is as good as it will ever get. You are trying to make a very good farm truck into a Ferrari. The 235 will most definitely finish the twenty four hours of LeMans but about 20 + hours later. I have had two double Rochester's on both Offenhauser/Fenton type intakes. I think it added about 3 to 6 horsepower and about 24 hours of work each week. Too much money spent on linkage, jets and experts. You can put a 68 Pontiac DOC and get better performance if you want H.P. from a six cylinder. Doc.
