I don't know about those carburetors, but I bought one from National Carburetors Inc. last year for $214.50 with no core charge. $90 seems like a lot for a core charge. The NCI carburetor I got had a stripped thread for the vacuum line in the base, so I had to return it for another one.

The carb I got sucks too much gas, but it does have a lifetime warranty, which I could not find anywhere else (don't know how good their warranty actually is.) I only bought this one because it was the cheapest around. My original leaking carburetor got about 11 mpg city and the NCI carb gets only 8 mpg city at best. It will get 11 mpg on the highway. (I have a 1983 C20 454, so pigging gas is a way of life for me.) I just needed something to get me through emissions and not leak gas.

I have read that Sean Murphy has good Qjets. I have had poor results with Carter(now Edelbrock) and auto parts store rebuilds, so I will go with Sean Murphy next time. A q-jet for my BB would cost $403.28 with shipping but it looks like no core charge.

I drive my truck less than 1,000 miles per year, so I can tolerate the low gas mileage for now. I will say that the NCI carb does start and run very well.
