    The perfect match for Dart small-block heads. A boundry layer of cool air beneath the plenum and runners insulates the fuel/air mixture from engine heat. This produces a denser intake charge and makes more power. The dual plane design maximizes mid-range torque, and a ribbed plenum floor promotes fuel atomization.

    • Recommended for 215cc and smaller intake ports
    • Accepts popular 4150 square carburetors
    • Dual distributor hold-downs to simplify timing adjustments
    • Raised water cross-over and air gap insulate intake charge
    • Integral bosses for nitrous injectors
