Just want a carburetor for a 1957, 292 ci with a 1957 Distributor, B-manifold and G-heads (I am told-???)  Something that just works well as I use it only for summer fun here in MN. Then store it in a igloo.   I have read many articles and just get confused so figured that those driving them would be a better source.  Thanks in advance.

I like the idea of smaller primaries for better throttle response at lower rpm and increased mpg. The Street Demon, however, didn't perform as well as other carburetors tested (including Summit's) on an episode of Engine Masters, but keep in mind that their focus is on max torque and horsepower, which is not necessarily the best indicator of how a carburetor will perform at various rpm on the street. Testing an engine on a dyno, under ideal conditions, is not a fair comparison.

I have a Holley 1848-1 465 CFM carburetor on my .060 over 292.  My engine has similar modifications to yours and is street driven. I chose this carburetor for a number of reasons.   I like the original look.  This carburetor is almost identical to the carb used on 1957 D code 312s. I am familiar with Holley carbs as I have been using them since I got my license in 1963. They are easy to tune, parts are available and they run great.  The other reason is this carb tested near the top of Ted Eaton's Y-Block dyno testing.  This did not surprise me as I am very pleased with it's performance.  A few other comments.  Throttle response is fantastic. This small 4V works perfect on a 292. I am running the stock jetting and secondary springs. My only modification was to install a manual choke.  My plugs are light tan and never foul.  Many of my friends run Summit carbs with good results.  I like the way my Holley looks and performs.
