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

BB Dave.

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

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

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.

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

I doubt that, seriously.

Very few '60's & early '70's big engine Musclecars would run 13's, on the street. Most ran 14's. My '69 366hp GTO would barely run 13's, with hard street tires, and that was with 3.90 gears. Would take some serious changes from a stock 326 Bird, to get the little 326 to run in the 13's, and still be streetable, IMO.

But hey, what do I know. There may have been 13 sec 326 powered Birds in almost every area that had a Pontiac dealer. I certainly never ran across one.
