Edelbrock part #29365 Victor FE EFI intake manifold is designed for high performance 390-406-410-427-428 c.i.d. Ford FE engines. The single-plane design provides race-winning power for many types of competition. Carb flange height is equal to the Ford high-riser manifold #C4AE-9424-G to fit under 427 Cobra hoods. Runners have plenty of material for port matching to low- or medium-riser style heads. Machined rear breather flange is included with unmachined nitrous bosses and front oil fill tube boss. Will not fit 427 high-riser and tunnel-port heads. Match with our FE heads.
