1990 Pontiac Firebird Formula 5.0 TBI from North America
On my 2nd radiator.
Used to be the show car for the Orion music company.
New front end assembly.
Transmission went out at 75,000 miles.
Not much off the line.
I can take corners at about 90 mph!
One thing I don't understand.
It shifts 6 times, 700 R4 6 speed auto?
If anybody knows why email me at email@example.com.
K&N air filter system makes about 10 more horse which put me up to 180?
That kinda sucks. Email me and tell me what ya think.
Would you buy another car from this manufacturer? Don't Know

Need more than a K&N, if you want cheap performance. Jet air foil, heavy duty cap, rotor, ignition wires, fabricated smoother air induction using PVC and cut pieces from the original tubing to make it work.
All this gave me 19 rear wheel ponies! Not bad for about a 100 bucks. Get a track auto cap and rotor, don't waste your money on a brand name, they are all the same.

I would sell it and get a 1990 with the 5 speed and dual cat exhaust. You will now have 230 horses to play with, and also have a chance against the mustangs...

It's the poor gearing that is doing it on your model. Also, the 5.0 TBI was one of the first OHV V8's to break the 25 mpg barrier -- something that makes more sense today than it did when this car was new! So it had only 170 hp, but it has tons of torque and is a penny-pincher on gas even by today's 5.0 standards.
