A single barrel stromberg will for ever be a reliable simple carbie bet will never return any kind of good economy. The 2 barrel webber as mentioned from the fords are a good carbie which can also improve power and economy. The main problem is they are still restricted by the manifold and although low and mid engine speeds will work well, you will get to a point where the carbie will want more air flow than it can get and the efficiency will go south. You will find that around 3/4 throttle where it really opens up, the air speed/volume won't be ideal for the carbie. This will of course most likely not be noticed when driving but you will be probably be running very rich and basically blow $$$$$$$ out the exhaust. The other problem is that there isn't a real lot of after market running bits for the ford type webber. On the other hand, although suffering the same basic problems as the webber, a 350 holley has an extensive range of tuning bits available. I have had some great success with a 350 holley on a holden 202, this is obviously a lot smaller and good inlet manifolds available but otherwise basically the same. The 350 is way tooooooooo big in standard form for a little holden 202 but with the accessories available it was modified and very successful with good dyno results to show. One of the biggest mods was the fitting of annular boosters into both throats to increase air speed and provide better atomisation. The same principle would be good with the 282 as they don't rev that much, good vacuum at low speed = efficiency = power. I personally believe that a carbie controlled by vacuum would be best overall as it will only give what the engine can use. Now although not exactly ideal as far as running extras go, a 2 barrel "varijet" of a VH commodore has a small primary throat and a BIG secondary controlled by vacuum so you have the small primary for good vacuum for low speed and economy and a vacuum controlled secondary for the big hills. They have a multitude of adjustments so are a good carbie if you know your way around it but overall can be a nightmare. I have been toying with the idea of possibly using an "SU" or similar. An SU is a full vacuum controlled carbie which once again will only give what is needed resulting in good power and good economy. The idea is replacing the pipe from the air cleaner to the original carbie with a new intake pipe, carb, 90 degree elbow and flange onto the original carb mount on the manifold. With a long runner, vacuum should be good at low speeds and engine torque should pick up. One other thing to consider would be for anyone wanting to still do some off road work may run into flooding problems on angles with some carbies.
