Item description
High-Quality Design: The 4MV features a robust build and precise engineering. It's a divorce/mechanical choke carburetor, meaning the choke is conveniently located on the intake manifold and connected to the carburetor via a choke rod.

Versatile Compatibility: Designed for Chevy/GMC trucks and cars from 1966 to 1973, this 4-barrel Quadrajet is compatible with various engines, including the 327, 350, 396, 400, 402, and 454. Bolt it directly onto any Quadrajet Spread bore GM-style intake manifold.

Easy Installation: While there are no included instructions, professional installation is recommended. The new carburetor arrives ready to install, but minor adjustments (mixture, idle, and float) may be necessary based on your specific engine and location.

Optimal Fuel Pressure: We recommend a regulated fuel pressure of 5 to 5.5 psi for optimal performance. If you're using a 7 lb or higher fuel pump, consider adding a fuel pressure regulator.

DIY Customization: Included extra jets allow for fine-tuning and modification. Use them if needed, but they're optional for most users.

Perfect Fit Guarantee: To ensure a precise fit, provide us with your carburetor's part number（Usually a 7-digit number starting with 7 or an 8-digit number starting with 17） and 3-5 pictures of the original carb. We'll confirm compatibility and help you achieve peak performance!
