    Even on a "mild" 460 I think I'd stick with an 850, but I guess the question(s) would be what RPM do you max out at and is it a stock intake manifold ?

    IMO you have virtually no use for anything bigger than a 750cfm'er, unless, and untill, you are spinning nearly 6-grand on that 460.

    Any "horsepower left on the table", is darned little, and throttle response, "driveability" is better with a smaller carb.

    850cfm hands down, is the carb you need.

    Thats about what my combo is. I have an over kill carb on my boat only becuase im going to build a bigger motor at some point. I have ran everything from a 650 to a 1050. The 850 will respond well and it wont drink a ton of gas.

    For your engine the Stealth intake is a good choice, what heads? I have a worked over 850 on my 429 CJ and like it.

    How about doing the math for a 460 cu in air pump. Guaranteed, anything under 8K rpm is not wanting that 850...............But hey, you're only wasting gas..............Ray

    well money pit, the question was "what are u running on your 460?'' According to holley's site ,I'm pretty much in the park. not saying your wrong ,but what is the math?
    I don't really get the tunnel ram thing? this boat had 2x600 cfm.doesn't that make 1200 cfm I was also told once"rule of thumb is CID x 2= cfm
