Quote:The V8 was designed by Oldsmobile and used in the 1961-63 Buick Skylark and Olds F-85 and in the Olds Jetfire turbocharged. I never heard they had overheating problems; more likely Rover fit too small of radiator? It was only a 3.5 liter, which was apparently too small for the american market. Buick had the V6 design of the same years in their Skylark. In 1964 they all went with the bigger V8s.

Buick then sold the V6 to Jeep ... and then later during the gas crunch bought it back and have been using it since 1975. This was the famous engine used in the turbo Buick Regal Grand National.

It was the Toyota jeep that used the Chevrolet-design straight-six. A tough but old engine design, but which makes it easy to bolt up a Chevrolet V8.
