1972 Pontiac Firebird Formula - Wingless Monarch
|
Only 276 Formulas were equipped with the optional LS5 455 H.O. engine. Conservatively rated at 300 net horsepower at 4,000 rpm with torque coming in at 415 at 3,200, this engine was an 8.4:1 low-compression screamer. Breathed-over 7F6 heads and a XE268H Comp Cam pump up the factory ratings without being uncivilized on the street. View Related Article
