    1964 401 Nailhead with 425 Intake

    Caleb installed this PML valley plate on his 1964 401 Nailhead with a 425 dual quad stock intake manifold. At first he thought the PML valley plate would not fit since the distributor hold down bracket was catching at the rear of the valley plate and keeping it from sealing. After he noticed that, the valley plate fit and looks great on the motor.

    Caleb plans to install a super wildcat air cleaner so he cut down the downtube to make more space.
