I would like your professional opinions on whether I should go back to the Rochesters or keep the Carter/Webers. | | |

I think if anything they are a bit too much carb (a pair that is)for the stock engines but i like the idea of secondaries on them so if you stay out of them they are about right and closer to a Rochester in CFM. What I don't like is the electric chokes but again, no real problems I would just rather have a manual steup.
Also a lot has been said about linkage problems but I had none and it was fairly easy for me, so go figure. What is easy for one is next to imposssible for the next person.
You asked for "professional opinions" but mine is just my own experience and I'm far from a professional. | | |

I should re-state the professional opinion and say that I would like anyone's opinion who has experience with the Carter/Webers. | | |

Linkage had to be lenghtened the height of the adapters but no big deal. Idle smooth, excellect acceleration and improved mileage (headers and duals probably helped here). Good choice as far as I am concerned

I would like to have a two barrel for economy and power but I don't want an electric choke. I'm looking for a manual choke, 2bbl carb, with slightly higher cfm ratings to the stock carb. I want to keep it as simple as possible.

I ran one on a 54 235 3 speed on column (3.70 gears) with HEI and stock exhaust and achieved 20 mpg while keeping up with traffic around town.
If you don't already have an HEI on it, that is the best thing I ever did to a stovebolt. I just put a PCV setup on the '55 235 in my 39 1.5 ton and gained another mpg.

the HEI is a good addition too. i put one on a jeep and it did wonders for power AND reliability. the idle went from none to perfect in the 2 hours it took to put it on! | | |

I think they are a great improvement over the old one barrel carbs. The problem with the 1bbl carbs is the newest one you can find is 40 years old and has been rebuilt at least once for every year it is old with wore out leaking guts. No openions here just facts. | | |
