This powerful V8, known for its torque and robust design, is a sought-after engine for restorations and performance builds. This guide will help you navigate the market, understand what to look for, and make an informed purchase.
What is an AMC 401 Engine?
The AMC 401, also known as the 401 cubic inch V8, was produced by American Motors Corporation (AMC) from 1968 to 1979. It's a large-displacement engine renowned for its impressive low-end torque, making it ideal for towing or powering larger vehicles. This engine saw use in various AMC models, including the Javelin, Rebel, Matador, and the iconic Jeep Wagoneer. While less common than some other V8s from the era, its unique character and performance potential make it a desirable engine for restoration projects and custom builds.
Where to Find an AMC 401 Engine for Sale?
Several avenues exist for finding an AMC 401 engine for sale:
-

-
Classic Car Parts Suppliers: Numerous businesses specialize in sourcing and supplying parts for classic American vehicles. Many will carry AMC parts, including engines, either rebuilt or needing restoration.
-

What to Look For When Buying an AMC 401 Engine:
Buying a used engine always carries inherent risks. Here's what to prioritize:
-
Compression Test: A crucial step is to request or conduct a compression test. This assesses the condition of the cylinders and rings, indicating the engine's overall health. Low compression suggests potential problems requiring significant repairs.
-
Leakdown Test: A leakdown test complements the compression test by pinpointing the source of any leaks in the cylinders. This helps determine whether worn rings, valves, or head gaskets are causing low compression.
-
Visual Inspection: Thoroughly examine the engine's external components for any signs of damage, rust, or corrosion. Check the block, heads, and accessories for cracks or significant wear.
-
Documentation: If possible, try to obtain any available documentation regarding the engine's history, maintenance records, or previous rebuilds. This offers insights into its past and potential future needs.
-
Price: Research comparable listings to establish a fair market price. Be wary of unusually low prices, as they might indicate hidden problems.
How Much Does an AMC 401 Engine Cost?
The cost of an AMC 401 engine varies greatly depending on its condition, completeness, and whether it's a bare block or a complete, ready-to-install unit. A complete, running engine will naturally cost significantly more than a bare block needing extensive rebuilding. Prices can range from a few hundred dollars for a project engine needing significant work to several thousand dollars for a fully rebuilt unit.
What are Common Problems with AMC 401 Engines?
Like any engine, the AMC 401 has some potential weaknesses:
-
Oil Leaks: Oil leaks are a common issue, often stemming from valve cover gaskets, oil pan gaskets, or the rear main seal.
-
Head Gasket Issues: Head gasket failure can occur due to overheating or age.
-
Timing Chain Wear: The timing chain can stretch or wear over time, potentially affecting engine timing and performance.
Can I rebuild an AMC 401 Engine Myself?
Rebuilding an AMC 401 engine is a substantial undertaking requiring mechanical aptitude, specialized tools, and technical knowledge. While possible for experienced mechanics, it's generally not a beginner-friendly project. Consider your skillset and available resources before attempting a rebuild.
By carefully considering these points and conducting thorough due diligence, you can increase your chances of finding a well-suited AMC 401 engine for your project. Remember to prioritize a thorough inspection and factor in potential repair costs. Happy hunting!
