QR Code Link to This Post The Buick V6, popularly referred to as the 3800 and initially marketed as Fireball at its introduction in 1962, was a large V6 engine used by General Motors. 225...The bore was increased to 3.75 in (95.3 mm), and stroke increased to 3.4 in (86.4 mm), increasing displacement to 225 cu in (3.7 L). Since the engine was similar to the popular small-block Buick V8 -- now with a cast-iron block and displacement of 300 cubic inches (4.9 L), the engine was made cheaply at the same factory with much of the same tooling. This engine was used in Buick's intermediate-sized Special and Skylark models from 1964 to 1967 and Oldsmobile's mid-sized F-85/Cutlass models for 1964 and 1965. 1964-1965 models featured a 1-barrel Rochester MonoJet, producing 155 hp. In 1966-1967, the 1-barrel was replaced with a 2-barrel Rochester 2GV, giving the engine a 5-horsepower boost to 160 hp. This engine did run when test fired. If you want something different in your hot rod or rat rod this is it. Sold as is. I have the 1962 Buick 198 mounted to a trike motorcycle that I built 2 years ago.
