The Pontiac Firebird underwent minor
changes for its second year.
There was a change in
the front turn lights to a wraparound style, both driver and passenger vent
windows were removed while Pontiac V-crest rear marker lights were added, the
Rally I rims were dropped from the options, the single-leaf rear springs were
replaced with a Pontiac-designed multileaf units (was not included on base
six-cylinder cars), the suspension system was improved by the new straddle
mounted shock absorbers, and the Firestone E70 Wide Ovals tires were upgraded to
F70 (did not include base six-cylinder cars).
There was also the midyear addition of the Goodyear Polyglas tire, the addition
of an optional new Power-Flex fan on all V-8s without air conditioning, the
deletion of the heater delete, and the deletion of the California emissions
equipment. The Firebird had a long list of standard equipment and options &
accessories. Along with the above changes and the addition of the Van
Nuys, California plant on March 4th, a few more changes were made including the
addition of a four-way power bucket seat.
The interior also saw new improvements with a larger padded instrument panel and
sun visors, windshield pillar moldings, crushable arm rests, flow-through
ventilation system with adjustable round air outlets on the lower dash, added
lower door panel carpeting, new instrument panel conical lenses and block
lettering, seat belts with push-button buckles for all passengers, anti-theft
ignition key warning buzzer, larger fuse block with eleven fuses, new bulkhead
electrical connector, and stronger door hinges of stamped steel.
The big news was under the hood. The standard 400 Engine gained 5 bhp to 330 while the Ram Air Engine was rated at 335 bhp. In mid year, it was replaced by the 340 bhp Ram Air II. Newly available was a third 400 V8, named the HO (High Output) that was slotted between the two other engines. The 400 HO cam with free-flow exhausts and its own revised cam (when mated to the four speed manual). It too was rated at 335 bhp. On the lower side of the model line, the 230 I6 was replaced by a new 250 I6 and the 326 V8s were replaced by new 350 V8s. Performance was definitely the key at Pontiac.
Six-cylinder overhead-cam increased from 230 cubic
inches to 250 cubic inches delivering 175 horsepower.

received a New Mono-Jet one-barrel carburetor. Prices
started at $2,666 for a coupe to $2,903 for a
convertible.
