Super Duty 421 Engine Top View
The Super-Duty 421 engine cranked out 405 hp at 5,600 rpm and 425 lb-ft of torque at 4,400. This beast was machined by Nunzi Romano and assembled by the owner. Displacing 433 ci, it features No. 980 cylinder heads, a compression ratio near 13:1, a radical mechanical camshaft from Nunzi's, and a points-type distributor likely used by Pontiac engineering. Pontiac's '63 Engine Production Log shows that just 59 code-13 engines were built that year.

Though a medium-rise dual-quad aluminum intake manifold topped by two 500-cfm Carter AFB carburetors would be correct for this application, Ken opted to install this rare two-piece 'bathtub' unit and a pair of correct 625-cfm Carter AFB carburetors onto the Catalina. Since there wasn't a factory air-cleaner produced for the application, Ken used screens like those found on the '69 Firebird Trans Am carburetor to filter incoming air.

Exhaust Manifolds Front View
To minimize weight, Pontiac cast the typical Super-Duty exhaust manifolds in aluminum. They weren't intended for normal use, however, and rumors of the pieces literally melting after a full-throttle run have floated about for years. Ken says the Catalina's originals have held up quite well, but he found a set in much better shape to install.

Exhaust System Front View
When closed, the stock exhaust system gives the Catalina a vintage sound, but Ken feels it's too quiet for his taste, so he leaves the collectors uncapped.

Suspension Front View
The frame was restored using DP90 semi-gloss black and the suspension was rebuilt using stock-replacement components. Shock absorbers are N.O.S. pieces. The exhaust system features a pair of N.O.S. Super-Duty mufflers and reproduction 2.25-inch head pipes and 2-inch tailpipes from Eugene Riotte of Ardmore, Oklahoma.

A copy of the Catalina's original manifest shows its unique assembly instructions. Note the production date of March 15 in the upper left-hand corner. General Motors pulled the plug on corporate-sponsored racing in January 1963.

Carpet Front View
Ken purchased N.O.S. material from SMS Auto Fabrics in Canby, Oregon, and had Fleetwood Automotive in Englishtown, New Jersey, reupholster the combination vinyl-and-cloth Aqua bench seat. SMS restored the original door panels, while a reproduction carpet from Auto Custom Carpets in Anniston, Alabama, was installed. The dashpanel and dashpad are completely original.

Dashboard Front View
The graceful styling of the Catalina's instrument panel might look unassuming, but the lack of a radio or ventilation controls indicate that this particular vehicle was built for competition. The odometer shows just 16,589 miles at the time the photos were taken, and Ken feels a majority of them were added a quarter-mile at a time.
