Description
Intended for high output, large cubic inch big block Chevy racing engines with 4.84 in. bore spacing, these Edelbrock Big Victor Spread-Port CNC heads are an improvement over existing designs. The casting is made from A-356 aluminum and is Hot Isostatic Pressing processed (HIP) for superior strength and durability, dimensional stability, and exceptional finish quality. These heads feature CNC-ported spread intake ports and a raised exhaust runner design for improved flow efficiency. The chambers are also fully CNC-ported and Edelbrock includes extra material in the deck to allow for fine tuning of the combustion chamber design if desired.Brand: Edelbrock
