1971 Pontiac Trans Am
1971 PONTIAC TRANS AM LARGELY CARRIED OVER
The ’71 Trans Am was carried over from the 1970 largely unchanged, with minor trim and detail changes, and countless upgrades mandated my new federal smog and safety regs. But the big new for 1971 was the availability of the 455 V8. Until 1970, GM had a mandate of its own that no midsize GM car could have any engine larger than 400 cubic inches (with the exception of the Corvette, of course), but that was lifted during the 1970 model year, opening the floodgates to a whole raft of big, big blocks. The new 455 came in two forms in the 1971 Pontiac Trans Am, the 325-horsepower L75, and the “HO”-version the LS5 with 335 horses. The 1971 Pontiac Trans Am came standard with the L75, with the LS5 being the only optional engine. The LS5, also known as the “455 HO” also came with Ram Air VI.
