The Holley 12-3646B Carburetor Base Plate is a high-performance solution for 1967, 1968, and 1969 Corvettes running a Holley 3x2 square bore carburetor setup. This base plate is meticulously designed and engineered to provide an optimal fitting and effective engine management.

Measuring 13.5 inches long and 15 inches wide, this cast aluminum base plate features three pre-drilled and sized mounting holes for the Holley 12-7101, 12-7102, and 12-7103 carburetor bodies.

This base plate is also compatible with Holley's optional accessory drives, including spark plug wires, fuel pressure regulators, coolant fans, and more.

A special provision is made for the vacuum secondary system commonly used on 1967-1969 Corvettes, allowing direct mounting of the carburetor vacuum secondary components to the base plate. This no-hassle design not only simplifies the installation process but also ensures proper vacuum secondary operation for optimal carburetor performance.

The Holley 12-3646B Carburetor Base Plate further boasts an excellent finish, making it a stylish addition to any restored Corvette engine bay. With its precision manufacturing and engineered design, this base plate is an excellent upgrade for Corvette enthusiasts seeking pure performance and the authentic appearance of their classic muscle car.
