Thus, in 1961, all Pontiac 215 engine blocks begin with "161P"; for 1962 the stamping began with "162P". Further code numbers indicated the car's transmission (manual or automatic). In 1961, the transmission choices were a three-speed column-shifted manual with a non-synchronized first gear, or a two-speed automatic transaxle controlled by a ...
The 215 V8 was also available on the Pontiac Tempest for 1961 and 1962 and used the Buick version, but very few Tempests were so-equipped. For 1962, Buick introduced a new 198 cubic-inch V6 engine for the lower-line Special models in order to allow for a lower base price.
During this period, Pontiac's intermediate lineup included the base Le Mans, Le Mans Sport Coupe, GTO (1973 only), Luxury Le Mans (became the Grand Le Mans in 1975), the Euro-styled Grand Am from 1973 through 1975, and on the 1977 Can Am.

The Trophy 4 engine is a short-stroke, 45-degree inclined [4] inline four created from the right bank of the 389 V8 for the debut of the Tempest in 1961. Its 194.43 cu in (3.2 L) displacement is precisely half of the 389, with an identical bore and stroke of 4 + 1 ⁄ 16 in × 3 + 3 ⁄ 4 in (103.2 mm × 95.3 mm).
The General Motors X platform (also called X-body) is a rear-wheel drive compact car automobile platform produced from the 1962 to 1979 model years. Developed by Chevrolet, the architecture was initially unique in the U.S. to the Chevy II, first joined by the Pontiac Ventura in 1971, then a range of other GM products as its divisions expanded their compact model lines.
Perhaps the most unusual variation of the Pontiac V8 was the 1961-63 Trophy 4, which was a 45-degree inclined 194.43 cu in (3.2 L) inline-4 created from the right bank of the 389 for the debut of the Tempest.
An optional Buick 215 cu in (3.5 L) V8, was not popular when it was available for 1961 and 1962 in the Tempest. For 1963, Pontiac replaced it with a new "326" that was actually 336 cu in (5.5 L) V8 with a bore of 3.78 and stroke of 3.75 (same stroke as the 389).
