    Default 1250 cfm dominator on a 535 BBB jet down power valve up

    I was told by an old racer buddy since I drive this on the street that I could change out solid metering blocks out and put power valve front and rear that I could drop 10 jet sizes , currently I have 94 square, and plugs look good after a Passat the track ( 1/4 ) and AF reads 13.2 cruising and mid 11ish WOT any body try it ??? my 535 is a 13.5-1 cr stage 2 cnc TA heads full 3" exhaust . car has run 10.70 @ 127 spun hard with a 1.55 60' but I like to drive it to car shows , this carb works well on street the way I have it set up now ..

    It will run better with a PV, much cleaner and crisper

    I've used them on the street with similar and slightly smaller CI engines and duals with that size or larger.
    Big cams and ported heads need a big gulp to satisfy the needs due to peak piston speeds.
    The linear calculations often used to guestimate CFM do not apply to these hungry beasts.
