( Brand: Gm ), ( Manufacturer Part Number: 3864808 ), ( Part Type: Valve Rod Block )
The 3946067 65 Valve 70 Rocker Rod Block is a crucial component in the engine of a classic Chevrolet Corvette or Camaro, specifically models from 1967 to 1972. This robust part is designed to house the rocker arms, which are responsible for converting the up-and-down motion of the valve lifters into the rotary motion needed to open and close the engine's intake and exhaust valves.
The 65 valve configuration refers to the number of intake and exhaust valves per cylinder, which in this case is three. The '70' in the part number indicates that this block is compatible with engines equipped with hydraulic lifters, as introduced in the early 1970s.
The block itself is made of high-strength materials to withstand the intense pressures and forces generated within the engine. It features a precise design with well-defined grooves and recesses to accommodate the rocker arms, pushrods, and other related components. The block is also designed to work seamlessly with the engine's camshaft, ensuring optimal valve timing and engine performance.
The 3608063 69 and 67 GM numbers are cross-referenced identifiers, meaning this part is interchangeable and can be used in both 1967 and 1969 Chevrolet engines. Additionally, the 3864808 68 Big Push designation suggests that this block may be compatible with engines that require a more aggressive camshaft profile, which can result in increased horsepower and torque.
In summary, the 3946067 65 Valve 70 Rocker Rod Block is an essential part for classic Chevrolet Corvette and Camaro engines, providing a stable and reliable platform for the rocker arms and pushrods to operate effectively, ensuring optimal engine performance.
