1972 Pontiac Firebird Trans Am Description

1972 Pontiac Trans Am, This is 1 OF 458 Trans Ams produced for 1972 strike shortened year. This PHS Documented Trans Am maintains is NUMBERS MATCHING DRIVETRAIN with SERVICE REPLACEMENT BLOCK and M22 ROCK CRUSHER 4 SPEED (SERIAL # STAMP) 7F6 HEADS (Rebuilt but not in Car ) ORIGINAL CARBURATOR AND INTAKE Interior was replaced by Current owner. Due to a 1972 UAW strike, at which GM was the target, Firebird and Trans Am production was devastated. All told only 1286 Trans Am's were completed V(828 automatics, & 458 4-speeds). At the plant, over 2,100 Firebird and Camaro models were in various stages of assembly when the strike ended, but as these cars would not meet the new 1973 Federal standards, these cars were all scrapped! The 1972 Trans Am production would hold the distinction of being the second lowest in history. A new cylinder head rested atop the 4-bolt block, this had a new casting number of 7F6 and was only used in 1972 and had special combustion chambers. The good part about these new heads is that they still used the horsepower producing oval ports and the accompanying large 2.11 intake and 1.77 inch exhaust valves found in big inch Pontiac high performance engines of the past. The 068 camshaft was back for another run in the TA, and the lift remained at .408/.406 inches for intake and exhaust. As in 1971, there was only one engine available in the Trans Am and it was subject to same hand selection of components in order to make the engines as close to the tolerances laid out in the blueprints. This engine could be mated to a pair of transmissions, the infamous M22 Rock Crusher Muncie 4-speed close ratio manual transmission or the sturdy 3-speed Turbo Hydramatic 400 automatic transmission. This was the 1st year for the honey comb grille, and the last year of a functional shaker hood. The colors once again remained limited to Cameo White with blue stripes or Lucerne Blue topped with a white stripe. Lucerne Blue would have its swan song in 1972 as a blue would not return to the Trans Am line up until 1974. The racing' stripes that were first introduced in '69 also made their last appearance in 1972 and no Trans Am would be striped as such until the 15th anniversary T/A in 1984.
