The Edelbrock Performer RPM intake manifolds for 330-350-403 c.i.d. and 1980-1/2 to 1985 307 c.i.d. engines with 5A heads (casting #3317) Oldsmobile engines feature a 180° firing order to produce significant gains in mid range torque as well as upper RPM horsepower while maintaining excellent throttle response. The cast aluminum construction features a high-rise, dual plane style with large plenums and runners that compliment street or competition engine modifications like headers, dual exhaust and upgraded ignition systems. An upgrade to a matching Performer RPM camshaft and cylinder heads will give you the ultimate performance advantage. Intended for street or strip high performance applications these intake manifolds do not feature provisions for emissions equipment or factory heat riser/divorced style choke.
