1979 Pontiac Firebird Formula Engine
|
The 220-horse 400 remains as the factory assembled it, with numbers-matching components from carb to oil pan. It has a cast bottom end, a 274/298-degrees duration cam with 0.364/0.364 lift and 1.50-ratio rockers, 8:1 compression, 2.11/1.66 valves in the 6X heads, a Q-jet carb, HEI, and an iron dual-plane intake and log-type exhaust manifolds.
