On the 67' Firebird 326 H.O.

A very-sharp car with the '326' call out emblem on the power-bulge hood, and
body-side stripe with the 'H.O' decal.

With a 11.02 Wt/Hp factor, it fell into the wrong end of
C/S in 1967.
But in 1968, with changes in Stock Class, it fell nicely
into G/S.

The 326 H.O. came through with the special body side stripe and
H.O. label.

A couple of little tricks, and you could get them to run high 13.00's,
and still drive them on the street.

Re: 1967 Pontiac Firebird

My first wifes first car was a '68 Firebird convertible 350HO 4speed, quite a performer.....

Re: 1967 Pontiac Firebird

BB Dave.

The Pontiac 350 was a very 'under-rated' engine..

The 1967 and 1968 Firebird were nice 'light' cars, and were good
performers.

Re: 1967 Pontiac Firebird

In 1968,,,

If you knew had to fit a car into the right NHRA Class -

The 1967 Firebird 400/325 HP 'convertible' was a 'perfect car' for F/S or F/SA in 1968 NHRA.
