Edelbrock Power Package Top End Kit 289-302 Ford 367 Hp

This Victor CNC cylinder head for Jeep 4.0L inline-six engines is a fully CNC-ported version of the popular 50169 Performer cylinder head Edelbrock has been producing for the past 19 years. The head features a 182 cc intake port, a 77 cc exhaust port, and a 55 cc combustion chambers. As an additional improvement the Victor CNC has a valve job to match up with the COMP Cams LS-style 8 mm valvetrain. Utilizing the LS-style valves opens a larger variety of valve spring combinations to fit any camshaft profile. These heads are manufactured with premium materials and machined to the industry’s tightest tolerances. Features include ductile-iron valve seats and fully CNC-machined ports for maximum airflow. The premium manganese bronze valve guides withstand long wear with emphasis placed on holding precision tolerances on valve seat concentricity to securely seal the valves, eliminate leak down, and increase cylinder pressures during engine operation.

This cylinder head will also swap onto all AMC Inline six 4.2L engines. This cylinder head must be used with a 1991-2006 intake manifold and a 1991-1998 exhaust manifold. Aftermarket exhaust headers can also be used in place of 1991-1998 exhaust manifolds and MUST be used in place of 1999-2006 exhaust manifolds. Most aftermarket exhaust headers are compatible, but please check with the exhaust header manufacture to verify. This head is NOT compatible with 1999-2006 OEM exhaust manifolds. This cylinder head will also swap onto all AMC Inline six 4.2L engines. However, this swap will require the use of a 4.0L 1991-2006 intake & exhaust manifolds. No modifications are required to the water jacket when swapping an Edelbrock Jeep Performer 4.0L head onto a 4.2L. This cylinder head is a direct bolt-on to 1991-2006 applications originally using 7120, 0360, and 0331 castings. This head will also bolt onto 1987-90 engines (2686 casting) with the 1991-2006 intake manifolds & 1991-1998 exhaust manifolds or aftermarket headers.

Edelbrock introduces its new Big Vic CNC 12-degree race head, specifically designed for maximum competition naturally aspirated, nitrous injected, and boosted applications. The Big Vic 12 is cast in the USA at Edelbrock’s state-of-the-art foundry, using a premium aluminum alloy that undergoes hot isostatic pressing for a more stable and dense grain structure. The large CNC oval ports and 2.500 x 1.800 valve job are specifically designed to maintain high airspeed for maximum cylinder fill during valve opening and generate a high torque curve throughout the engine’s operating range. Manufactured with premium materials and machined to the industry’s tightest tolerances, these heads feature a 12-degree valve angle, copper valve seats, and fully CNC-machined 498cc ports and 82cc chambers to increase overall airflow capability. The premium manganese bronze valve guides withstand long wear with emphasis placed on holding precise tolerances on valve seat concentricity, allowing the valves to seal securely to eliminate leak-down and increase cylinder pressures during engine operation.
Edelbrock’s Big Victor cylinder heads are made with premium HIP aluminum alloy. They feature 498cc raised intake ports, 82cc chambers, and 2.500″ / 1.800″ Ex valve job.
