Rocket engine
Oldsmobile also introduced the Jetstar I for 1964. Not part of the Jetstar 88 line, the Jetstar I instead was a direct competitor to the Pontiac Grand Prix in the same $3,500 price range. Jetstar I's shared the notchback body style with the Starfire along with its more powerful 394-cubic-inch Rocket V8 engine, but with less standard equipment and a lower price tag. Oddly, Oldsmobile teamed the Rocket engine with a very unsuitable transmission in the Jetstar I, the Jetaway (Super Turbine 300) two-speed unit with "switch pitch" converter.
