1963 Pontiac Catalina
The year before the GTO arrived and redirected Pontiac’s performance story toward intermediates, the top street weapon in the full-size lineup wore a Catalina badge.
For 1963, the Wide Track body received cleaner, squared-off lines and vertically stacked dual headlights flanking the trademark split grille, a sharper look than the 1961–62 generation it updated.
The two-door hardtop was the natural pairing for the optional 421 HO, the most powerful regular-production street engine Pontiac listed that year. Displacing 421 cubic inches, it drew air through three Rochester two-barrel carburetors (Pontiac’s Tri-Power arrangement) and produced a factory-rated 370 hp at 5,200 rpm and 460 lb-ft of torque at 3,800 rpm, with 10.75:1 compression.
The standard transmission with the 421 HO was a heavy-duty three-speed manual, with a four-speed manual optional, and Safe-T-Track limited-slip was available. The Borg-Warner T-10 four-speed handled shifting duties when so equipped, and 8-lug aluminum brake drums were optional.
Pontiac built 3,200 421 HO engines for full-size models in 1963 (engine code 11B), with 421 Super Duty production separate from that figure. This example is finished in Marimba Red Metallic with the optional Ventura tri-color red bucket-seat interior.
