BCBC V0399 Engine Intake Valve

Engine Intake Valve Overview

The Melling V0399 is a standard replacement engine intake valve built for a wide range of classic Chevrolet, GMC, Buick, Oldsmobile, Pontiac, and Studebaker applications. It uses steel construction, a coated finish, and standard-size stem dimensions to match stock-style valve train requirements.

Compatible With Chevrolet Camaro, Chevrolet Chevelle, GMC C/K truck applications, and many other stock engine builds listed below. The V0399 intake valve is intended for engines that need a direct replacement valve with the correct head diameter, stem size, and seat angle for proper sealing and airflow.

• Steel valve construction for durability in valve train service
• Coated finish for added surface protection
• Standard replacement grade for stock-style engine rebuilds
• 45-degree seat angle for common OEM-style valve seat geometry

Detailed Fitment and Design

Part number V0399 is engineered with a 1.72-inch valve head diameter, 0.341-inch stem diameter, 4.912-inch length, and two lock grooves. Those dimensions make it a fit for many stock and standard-size stem applications across Chevrolet and GMC trucks, vans, and passenger cars, including Chevrolet Camaro and Chevrolet Chevelle platforms.
