History of the Pontiac 400 V8
For 1967, Pontiac introduced the 400 in?? (6.6 L). The 400 V8 was a bored-out 389 with 4.121 inch bore and 3.75 inch stroke (104.7 mm by 95.3 mm). It replaced the 389 and remained in production through the 1979 model year

Ram Air V - In 1969 Pontiac created several versions of their "tunnel port" engine: a special short-deck version of the V8 for Trans Am racing and a 400 standard deck version. The factory also experimented with 366 and 455 in?? versions. The cylinder head was patterned after the highly successful Ford 427 tunnel port head. So large were the intake ports that the pushrods ran through the center of the ports via pressed-in tubes.
