    A good dual plane intake , larger TBI , mild upgrade hyd roller cam
    and an optimized [ for changes] OE Chip will run real strong, for less
    time and expense of changing to port injection system.
    The stock 4.3 TBI Intake leaves much to be desired by way of efficient
    mixture handling and velocity. With the right combination, a 4.3 TBI combo
    will fly.
