About “Land Shark”

My wife (BigBlueBonnie) gave me this car for a Christmas present. She is awesome.

It is a 1963 Grand Prix with a 421 HO engine, with tripower and a 4 speed.

Many car enthusiasts today didn't know Pontiac made a 421 CID engine and what that engine really was. In 1963, there weren't any GTOs, Camaros, Mustangs or Chargers prowling the streets. If you wanted a muscle car, you got a full size car with a monster engine. The 409 Chevy, 413 Mopar and 421 Pontiacs ruled the streets. The 421 HO Pontiac engine with the tripower was one of the best back then. It was the first of the large journal Pontiac V-8s, the grandfather of the 455.

It isn't a big block. Pontiac never made small blocks and big blocks. Every Pontiac V-8 from the first 287 in 1955 to the last 455 had the same external dimensions.

Yes, Land Shark is big, loud and fast. I stomped a first generation Camaro in some stop light drag racing during the test drive.....twice! The Camaro passenger kept looking over at the Grand Prix and asking the driver "What the h*ll is in that thing?"

The car features power steering, power brakes, power antenna, a Deluxe AM radio with rear speaker and 8 lug wheels.

The name (Land Shark) was bestowed upon her by WildWIlliam, who I was following one evening after a car show. He had his top down and said it was like a Land Shark following a minnow.
