The Pontiac Le Mans was a model name applied to compact and intermediate-sized automobiles marketed by the Pontiac division of General Motors from 1962 to 1981.

For 1968 the whole Tempest line received a new engine replacing the 326. This new engine was based on all existing Pontiac engine architecture and using the 326, 389, and 400 engines crank at 3.75″ and expanding the 326’s 3.72″ bore to 3.88″ to give 354.74 cubic inches. Why Pontiac called it a 350 is a mystery along with the original 326 being called a 326 rather that its true size of 336. For 1968 the 350 could be had in two versions at 265 hp 2bbl and 325 hp 4bbl. In 1969 the engine came as 265 hp 2bbl and 330 hp 4bbl. The ten horsepower increase over 1968’s engine is due to a slightly hotter cam plus the use of the # 48 big valve heads, the same head used on the Ram air 3 400″ 366 hp (273 kW) engine and the 428-HO engine at 390 hp.
