Used Buick Riviera Engines


Used Buick Riviera Engines engines



The Buick Riviera was manufactured from 1963 through 1999 by General Motors. It was in a class known as personal luxury cars. Ford had enjoyed enormous success with the introduction of the Thunderbird and the Riviera was designed to compete directly in this class.


Sales were sagging for Buick and they were looking for something new and fresh to stimulate interest in the Buick name. The Riviera project was seen as something that could revive flagging sales. The first Riviera's featured a 445.5 wildcate 401 cu in Nailhead V8 engine with automatic transmission. Later in this first generation Riviera, a 425 cu in Nailhead V8 engine would also be offered. This particular model would be known as a Gran Sport Riviera. The Buick Riviera would see many design changes throughout the sixties and into the seventies.
