While the much more interesting "letter series" Chrysler that year, the 300J, had the badass Golden Lion 413cid "Wedge" engine with dual quads on those wild-looking Ram Induction manifolds, it was only available as a hardtop.
Consequently the 1,861-vehicle run of 1963 Pace Cars were built on a regular 300 convertible, with the 305hp 2-bbl Firepower 383 V-8 and a pushbutton-shifted TorqueFlite three-speed automatic.
