What Makes the AMC 401 Engine So Desirable?
The AMC 401 cubic inch V8, produced from 1968 to 1979, holds a special place in automotive history. Its large displacement translates to substantial power and torque, making it ideal for muscle cars and heavy-duty applications. While not known for its high-revving capabilities like some competitors, the 401's low-end grunt is legendary. Its reliability, when properly maintained, adds to its appeal among classic car owners and enthusiasts. Many consider the AMC 401 a robust and relatively simple engine to work on, which appeals to those comfortable with engine maintenance and repair.
Where to Find an AMC 401 Engine for Sale?
Locating a suitable AMC 401 engine for sale can involve exploring various avenues:
- Online Marketplaces: Websites specializing in classic car parts and engines, like eBay and specialized forums dedicated to AMC vehicles, are excellent starting points. Thorough research of seller reputation is crucial. Examine feedback ratings and look for sellers with established histories.
- Classic Car Parts Suppliers: Many businesses specialize in supplying parts for classic cars, including engines. These suppliers often have a broader selection than individual sellers and may offer warranties or guarantees.
- Local AMC Clubs and Forums: Engaging with local clubs and online forums dedicated to AMC vehicles can connect you with owners who might be selling parts or complete engines. This method offers the chance to interact directly with fellow enthusiasts, often leading to valuable insights and advice.
- Junkyards and Salvage Yards: While this option requires more legwork, you might discover a hidden gem – a usable AMC 401 engine – in a local junkyard or salvage yard. Be prepared to inspect the engine carefully for any signs of damage or wear.
What to Look for When Buying a Used AMC 401 Engine
Buying a used engine involves a level of risk, so careful inspection is paramount. Here's a checklist to guide you:
- Compression Test: A compression test is vital to assess the health of the engine's cylinders. Low compression in one or more cylinders suggests potential problems that could lead to significant repair costs.
- Leakdown Test: This test helps identify issues like worn piston rings or valve problems. A leakdown test provides a more comprehensive picture of the engine's internal condition than a compression test alone.
- Visual Inspection: Thoroughly inspect the engine for external damage, corrosion, rust, and signs of previous repairs. Pay close attention to the block, heads, and any external components.
- Documentation: If possible, obtain any documentation regarding the engine's history, maintenance records, and previous use. This information can provide valuable insights into its condition.
- Ask Questions: Don't hesitate to ask the seller detailed questions about the engine's history, reasons for sale, and any known issues. A transparent and informative seller is a good sign.

Remember to factor in shipping costs if purchasing from a distant seller.
What are the common problems with AMC 401 engines?
AMC 401 engines, like any other engine, have some potential weaknesses. These often include issues with the oil pump, camshaft, and rocker arms.
