Pontiac Firebird 1973 Description


I've had it for 10 years, drove it quite a bit and decided to put it away and upgrade/restore about 6 years ago. Non op now

You absolutely feel like the King Of the Road driving it

Awesome V8 sound, very street able big power engine:good smooth idle, smooth acceleration through rpm rang, no flat spots, very civilized mod with a lot of usable power.

400+ HP

High compression pistons (10.5:1)

New Engle mild performance cam

Rebuilt top end

Roller rockers

Holley 750 (just rebuilt)

Victor Junior intake manifold

Full headers

dual 3 “ flow master exhaust

MSD ignition and distributor.

Less than 5K miles on suspension:

Newer bushings, ball joints, tie rod ends.

Posi traction rear end,

Center Line billet wheels

New BFG tires

Newer respray but poorly prepped so it needs a do over (paint job) for show.

California car with very little rust see pics :

little on fenders attachment inside engine compartment

lower right quarter

Right side B pillar by the roll up window.

Small spot on the lower left fender behind the wheel well.

That's all I found.

Super solid zero rust floor pans, rockers, doors, trunk, wheel wells.

This as an AC car however it needs condenser, compressor and hoses to work.

Going another direction with my cars.
