1974 Pontiac Firebird

1974 Pontiac Firebird Trans Am

The 1974 Pontiac Firebird was a difficult year for the Firebird. Gone was the Endura bumper, replaced by new, Federally mandated, fiberglass front end with a slight wedge shape and rubber covered 5 mph bumpers. The chrome rear bumper was also gone, replaced by those pesky rubber bumpers. Engine ratings dropped again with the Trans Am’s base 400 V8 engine rated at 225 bhp.

But for a mere $57, buyers could order the 250 bhp 455 V8, which received a 10 lb-ft boost to 380 lb-ft, but which came only with an automatic transmission. The mighty Super Duty 455 V8 was also available for an additional $578 and were unchanged from the year before. All V8s included true dual exhausts, which made their last appearance on the Firebird.

Also available for the last time on the 1974 Pontiac Firebird was the Muncie 4-speed manual transmission and the TurboHydramatic 400 automatic transmission. The lower output of the 1975 engines would make those heavy-duty transmissions unnecessary. This would also be the last year of the Super Duty engines.

For 1974 Pontiac Firebird, a brand new front end was introduced due to bumper regulations with a slight wedge shape and a revised rear end with a body-color bumper and longer slotted tail lamps. Engine ratings were changed, but the model lineup continued to remain the same.
