421 Cubic Inch High Output Classic Muscle Car From the Pontiac Motor Division. The Men at Pontiac's High Performance Development were hard at work by 1962, burning the mid-nite oil and dreaming up plans that would eventually be the ground work for the 389 cubic inch powered Tempest Le Mans, which in turn would evolve into the Iconic GTO and the "Muscle car" era as we know it was born. To state these few men were "Gear Heads" is an understatement. They were Hot Rodders thru and thru, true to there hearts, and that's what makes this Full Sized Catalina Coupe so special. The very same Pontiac "young guns" were the inspiration behind the development of the early 4 Bolt Mains Big Blocks before the GTO was ever a production Muscle Car. They were way ahead when it came to "Muscle" under the hood. And this Beautiful Catalina is Proof of this with a whooping 405 HP and 480 Ft. Lbs. of Asphalt Thumpin' Torgue , this Detroit Special will definitely Haul the Mail and Then Some. We bored the 1966 block .052 oversize and fitted high compression pistons from a 428 cu. in. Big Block so this Catalina is approximately 433 cubic inches;We used Racetech 10.5 to 1 high compression Pistons and a XE256 Competition Cam with .447" lift; The Edelbrock Aluminum 'D' Port Heads are fitted with Pontiac's High Output cast iron exhaust manifolds; The Edelbrock Heads are A356 aluminum heat treated to T6 specs for superior quality and performance; Fully CNC Ported and fitted with 2.11" diameter intake valves and 1.66" exhaust vales, combustion chambers are 72cc's; the re-positioned spark plug holes are aimed directly at the exhaust valves for complete efficient burn for max Torgue and maximum low end power; Maximum Torgue is 479.6 Ft. Lbs. @3500 RPM, while Max. HorsePower is 405@ 4900 RPM on the Dyno running through full mufflers!The Transmission is a GM Turbo 400 w/ modified valve body and a 2200 RPM Stall Converter; The Ignition is provided by a MSD Digital a6 with a MSD Blaster 2 Coil for optimum Spark at the plugs; The Frame-Up Restoratation began by complete wire brushing the chassis down to bare metal and then a Sikkens Product Chassis Primer followed by several coats of Sikkens Satin Black Chassis finish, all brake hard lines were replaced along with OEM Brake hoses and new wheel cylinders, then onto the Fuel lines and Hoses while the Fuel Tank was Hot Tanked and re-coated to alike new finish. Being a Texas Car this Catalina has a very clean, straight, rust free body that provides the near perfect panels to wear the original Cameo Ivory White bottom and the original Madera Red Top finish it had when it left the assembly line in 1963; Equally nice is the interior including seats, panels and carpeting, all original and all in very good to excellent condition. Finally we get to the magnificent OEM 8 Lug two piece wheels that were Iconic to fast Pontiacs of the era and this Catalina is plenty fast, believe me. Just the powerful sound gives a very honest indication of the awesome power under the hood. You won't be disappointed with this car, it's a true survivor and a head turner wherever it is, moving or stopped or parked. A great example of an early American Muscle Car, all packaged in a family size coupe, great for taking the kids out on "Cruise Nights" at the clam shack.
