Blower carb

I have a Weiand 142 ready to bolt on a Chevy 350 when I get around to it. The Weiand website has a some good info on their blowers (B&M is essentially the same as Weiand).

The blower on makes boost when under acceleration, so you can get good gas mileage if you resist the urge to use all that power every time you accelerate. The biggest danger is having the carb run lean, leading to predetonation and the end of your blower and engine.

Weiand recommends a "boost referenced" carb and specs which one should be used with their blower. I believe a good carb shop can get the primary power valves boost-referenced on most any carb you want to use. I just purchased what Weiand recommended.
