1991 Pontiac Firebird FORMULA 5.0 LO3 from North America
This is a serious long term owner vehicle as the engine can last over 200,000 miles
When purchased, nothing.
After basic tune-up, the idle was rough. Found base timing was off and the timing was off 6 degrees. A vacuum leak was found too. Since then the car has a smooth idle.
Easy to mod. This 5.0 is awesome with my few upgrades. 300 pound/ feet of torque now.
This interior has withstood 16 years of use and still remains in seriously excellent condition.
I can't roll anywhere without compliments.
I did a formula clone to the base model and looks really awesome.
Many part dealers for this car!
Gas mileage is better with the headers though.
Still have the original struts and are working fine!
Would you buy another car from this manufacturer? Yes
