I used one for several years with good results. Mine had an electric choke that worked well. The only thing I can think of in it's disfavor was that mine was a 4160 rather than a 4150. That means that it has a secondary metering plate where the secondary jets are fixed and not replaceable for tuning purposes. Holley does make a kit however that converts the 4160 to a 4150 with the secodary metering block that does allow changing the secondary jets for more tuning ability.
