Thread: Selecting right carb - 440 Mopar.

    Default Selecting right carb - 440 Mopar.

    Hello all. I have a 446 CI big block Mopar in a 4 speed Coronet. I have a 3.73 gear with a 28” tall tire on the car. Car weighs around 3600
    The engine is:
    -9.5:1 compression
    -Holley Street Dominator intake
    -Pertronix ignition 20° base, 34° all in.
    -Ported 906 iron heads that flow 295 on the intake. 2.14” valve
    -Cam is 234°, 240° @ .050 .530" lift on a 109° LSA.
    -Vacuum in 10” to 12” at idle

    I use the car as a street car with an occasional trip to the strip.

    I’m considering an HP 80511-1, 830 CFM with annular boosters.
    The intake heat crossover is blocked.
    I thought the annular boosters would help the low end and the 830 would still give me good top end. Does that sound like a good choice? Thanks.

    Yes, that sounds like a good choice. Gary
