The 3.8 liter engine was a V6 back then. It was created from an aluminum V8 in the GM’s stable of engines. This powerful “Fireball” displaced an incredible 198 cubic inches since it shared tooling with the aluminum V8.

At the end of 1963 the bore was increased, which increased the displacement to 225 cubic inches. That was the same displacement found on the 300 V8. Since the 3.8 liter had the same bore as the 1966 340 V8 it could be produced on the same assembly line. That made it relatively easy to produce in car terms, plus combining it on the production line reduced the cost. GM was able to use the 3.8 liter to sell its compact models as well as the flagship Buick.

Back in those days the demand for the V6 model was less than expected so GM sold the design to Jeep in 1967. The gas crisis hit in the 1970s so the demand for inexpensive, lightweight, and versatile engines increased. Buick bought back the 3.8 litre V6 design from Jeep in 1974. With a little tweaking Buick was able to produce the 3.8 Litre V6 on the same assembly line as the 350. The engine shared the same pistons and other parts and still retain the “odd-fire” design.
