A guy around here is selling one. Its black, auto, 350 tpi, slip, need paint and some finerglass on the spoiler. He is asking 3,000 for it.
Is it worth it, what did they run?

$3,000 sounds good to me. i'd take it. My friend payed $2,000 for his 86 I-ROC and it only has a 305 and needs paint. As for the Formulas, i believe that a 350 formula should run a low 15, high 14? don't quote me on that, but i saw one at the track, red with gold rims, and it ran a 14.3, he said all he had was exhaust and headers. Sounds good to me though. Good luck.

I say you should bid your time. I waited and waited and got a good deal. I got mine for $2700 and it didnt need fiberglass or paint. You will find one at a better price if you wait.

They are nice cars!

I wouldnt call it rare, but they are still nice. They should run somewhere in the mid 14's if in good tune, and there is a lot of room to grow. I say make an offer if you are interested. The worst the seller can do is say no and ask for more money.

Car: '91 Formula
Engine: 350
Transmission: TH350 built
Axle/Gears: 3.73
I paid $5500 for my 91 Formula 350 about 3 months ago. The body is almost perfect, only a few rock chips on the hood, with original red paint. The interior is perfect, no rust on the bottom. It had 79,000 miles. I felt like it was a fair price. With a few minor mods (airfoil, fastchip, open K&N) and a tuneup Ive run 2.09 60' and 9.06 in the 1/8, 76.5mpg. I love the car and plan on building a 388, 425HP motor for it soon, and keeping it forever. Its not a daily driver fortunately. I guess they are not that rare but I don't see many like it around here. I think it could be a semi classic someday, the asymetrical hood makes it different.

I paid $3000 for my 1990. I like it alot. I've heard of 90-92 (SD cars) Formula 350s running mid 14s stock.

The Formula 350's are a little rare to see but there are plenty of them around. A stock Formula could run a 14.4-14.6 at best with a very good driver. They tend to run good times because they have no ground effects and not as many options as a Trans Am, which looks and handles better.

Do you mean the Formula looks and handles better, or the trans am. I think the car looks better without the ground effects. The z28 ground effects look good, but the Firebird ones look funny to me somehow. I dont think either do anything for handling unless you get up to about 140 mph. Besides I heard the stock wing on the transam/formula will actually cause the car to be less stable at high speeds. YOu have to get a real wing which apparently are available. The formula I have has the WS6 package and say "performance suspension" on the dash. I think it would handle as good as a transam although ive never actual driven a transam. the way I understand it is the formula (equipped like mine) has the same power and handling options as the transam, but doesn't have all the bells and whistles, which makes it lighter and faster.

i dont know about the T/A wing making it not as stable at high speeds. the design was taken directly from Dennis Mecham's MACHO Trans Am race cars of the early 80s. they tested the car with and without the wrap-around spoiler and when the car had it on, it helped considerably

That 90 style wing is good for speeds in excess of 300mph.


"We also run the stock rear spoiler from a 1990 Pontiac Firebird on our 1992 car because we feel that is the best spoiler that Pontiac has. It’s not an aftermarket spoiler, it’s an actual stock rear spoiler and it’s the one that starts on the glass itself and goes all the way around the deck lid."

"If you’re going to go 300 mph in a stock-bodied production car at Bonneville, the car of choice is a Pontiac Firebird," said Joe Kugel. "Out of all the production cars, it probably has the lowest drag as far as aerodynamics are concerned, and at 300 mph, this Firebird has to be the most stable vehicle that’s ever been built.


This is the worlds fastest factory bodied car.

I am shooting for 200mph with my Trans Am. I just want to hit that number once so I can be a member of the "200mph Club".

the 85-90 wings are not the wings in question

the 91-92 t/a wings are said to have caused a lift of the rear end on high-speed runs.

How's it going Larry? You going to be at the James Coney this Saturday?
