    I just completed a switch from a stock QuadraJet Carb to a Holley 600 Carburetor on my 1985 C10. Wow, what difference!! Gas mileage went from 12 MPG to 16 MPG and the performance is WAY better. I have a list of replacement parts used if anyone is looking to replace their QuadraJUNK for a Holley.

    I have been thinking about switching my 4brl Qjet with a holley carb but was told by a guy it wasn't worth it.. This isn't true im guessing? Its my daily driver and id like to see a little gain in power and maybe mileage. I was thinking about getting a 650 myself. Any thoughts?
