Description
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.
