CLASS RACER FORUM - View Single Post - 1973 Pontiac Firebird Formula 455-SD

I have a very good friend who is a Pontiac addict. He owns several '70-'77 Firebirds, one of which is a '74 Formula SD 4-speed that he restored. It was a low-mile car with all the original parts to begin with so the restoration was easy. Right after he bought it, we tooled around in it one evening and I was pleasantly surprised how much power that car had. The PO had installed headers and had some distributor-carburetor tweaking done, but it was basically stock. It helped me understand the mystique of the SD. The car is dark blue with factory leather interior (I didn't know they made such in 1974!) but without the 455-SD stickers on the hood, no indication what it is.

My favorite car he owns is a '71 455 HO that he smoked over with a lot of suspension mods and a motor that did 584 hp on the dyno. Lots of fun and will make you think you are a Trans-Am racer on open roads. He also owns the most optioned '69 GTO ever documented.
