The Enduring Legacy of the AMC 360 V8

Before diving into the buying process, it’s crucial to understand what makes the AMC 360 so special. Developed by American Motors Corporation (AMC) in the late 1960s, the 360 cubic inch (5.9L) V8 was part of AMC’s popular Gen-2 V8 family. When AMC acquired Kaiser-Jeep in 1970, the 360 became the premier V8 option for Jeep’s full-size models, quickly earning its "Jeep 360" moniker in the popular lexicon.

It powered a wide range of vehicles, including:

• Jeep Wagoneer/Grand Wagoneer (SJ): The epitome of luxury SUVs for decades.
• Jeep Cherokee (SJ): The full-size predecessor to the XJ, a capable off-roader.
• Jeep J-Series Trucks: Workhorses designed for hauling and towing.
• Jeep CJ-7 and CJ-8 Scrambler: Later models offered the 360 as a factory option, transforming them into formidable performers.

Known for its robust cast-iron construction, strong low-end torque, and relatively simple design, the AMC 360 was a workhorse. Its carbureted nature made it easy to diagnose and repair, and its impressive torque output made it ideal for heavy vehicles and off-road applications. While not a high-revving horsepower monster, its reliability and grunt ensured its place in the hearts of Jeep enthusiasts, making it a continuously sought-after engine even decades after production ceased in the early 1990s.

Why Acquire a Jeep 360 Engine Today?

The reasons for seeking a "Jeep 360 engine for sale" are varied, but generally fall into these categories:

• Direct Replacement: The most common reason is to replace a tired, damaged, or seized original 360 in a classic Jeep. Keeping the original engine type preserves the vehicle’s authenticity and often simplifies the swap process.
• Engine Swaps: The 360 is a popular choice for swapping into other Jeep models (like earlier CJs that came with inline-6s or even some YJs), or even other classic vehicles that benefit from its compact V8 power and readily available parts.
• Restoration Projects: For purists undertaking a full, period-correct restoration, a meticulously rebuilt or original 360 is essential.
• Reliability and Simplicity: Compared to modern, computer-controlled engines, the AMC 360 is mechanically straightforward. This translates to easier troubleshooting, lower maintenance costs for DIYers, and a classic driving experience.
• Cost-Effectiveness: While not free, a well-rebuilt 360 can often be more cost-effective than attempting a complex modern engine swap, especially when considering all the necessary adapters and electronics.

Types of Jeep 360 Engines Available

When searching, you’ll encounter various classifications of AMC 360 engines, each with different implications for price, condition, and readiness:

1. Used / Pull-Out Engines:

   • Description: These are engines removed from donor vehicles, often salvage cars or trucks. They come "as is" with unknown mileage and service history.
   • Pros: Cheapest option, good for those on a tight budget or seeking a core for a rebuild.
   • Cons: Highest risk. May have significant wear, internal damage, or require extensive rebuilding. Condition is often a gamble.
   • Best For: Experienced mechanics, those planning a full rebuild regardless, or seeking specific components.

2. Rebuilt / Remanufactured Engines:

   • Description: These engines have been disassembled, inspected, had worn or damaged components replaced (e.g., pistons, rings, bearings, camshaft), and reassembled to factory specifications or better.
   • Pros: Often come with a warranty, significantly reduced risk compared to used, closer to "new" performance.
   • Cons: More expensive than used engines. Quality can vary between rebuilders, so reputation is key.
   • Best For: Most enthusiasts looking for a reliable, ready-to-install engine without the uncertainty of a used unit.

3. Crate Engines (Performance/Custom):

   • Description: These are brand-new or extensively modified and upgraded engines built for specific performance goals (e.g., increased horsepower, torque, specific applications). They often feature aftermarket components.
   • Pros: Highest performance, often dyno-tested, brand new components.
   • Cons: Most expensive option, may require specialized tuning or supporting modifications.
   • Best For: High-performance builds, serious off-roaders, or those who want a fully customized and optimized engine.

4. Long Block vs. Short Block vs. Complete:

   • Short Block: Consists of the engine block, crankshaft, connecting rods, and pistons. It’s the bare minimum for the rotating assembly.
   • Long Block: Includes the short block plus cylinder heads, camshaft, and valvetrain. It’s usually what people mean by a "rebuilt engine."
   • Complete Engine: Includes the long block plus intake manifold, carburetor (or fuel injection), distributor, exhaust manifolds, oil pan, and often accessories like the water pump, alternator, and power steering pump. This is the most "drop-in ready" option.

Where to Find a Jeep 360 Engine For Sale

The hunt for a good AMC 360 can lead you to various sources:

• Online Marketplaces:

  • eBay: A vast selection, from used pull-outs to rebuilt units. Be wary of shipping costs and verify seller reputation.
  • Craigslist/Facebook Marketplace: Excellent for local finds, allowing for in-person inspection and avoiding shipping fees. Exercise caution and meet in public.
  • Specialized Forums: Jeep forums (e.g., IFSJA, Pirate4x4, Jeepforum) often have "for sale" sections where enthusiasts sell parts, including engines. These communities can offer valuable insights and reputable sellers.

• Salvage Yards / Auto Recyclers:

  • These are primary sources for used pull-out engines. Call ahead to inquire about availability and condition. You might get lucky and find a running donor.

• Engine Rebuilders & Suppliers:

  • Many reputable companies specialize in rebuilding classic American V8s, including the AMC 360. A quick online search for "AMC 360 rebuilt engine" will yield results. These are often the best source for warrantied long blocks.

• Local Mechanics & Restoration Shops:

  • Shops specializing in classic Jeeps or 4x4s may have connections to good cores, or even rebuilt engines for sale. Word-of-mouth referrals can be gold.

Key Considerations When Buying

Purchasing an engine, especially a vintage one, requires careful diligence. Here’s what to look for and ask about:

• Condition is King:

  • For Used Engines:
    • Visual Inspection: Look for severe rust, cracks in the block or heads, signs of coolant/oil mixing (milky oil), or significant external damage.
    • Compression Test: If possible, perform a compression test (or have the seller do one and provide results). Consistent readings across all cylinders are a good sign. Low or uneven compression indicates internal wear or valve issues.
    • Oil Pressure: If it’s a running engine, ask for a video showing oil pressure at idle and under throttle.
    • Fluid Condition: Check the oil and coolant for cleanliness and absence of metallic flakes or sludge.
    • Listen for Noises: If it runs, listen for knocking, ticking, or excessive rattling.
  • For Rebuilt Engines:
    • Warranty: A reputable rebuilder will offer a warranty (e.g., 1-3 years/unlimited mileage). Understand its terms and what it covers.
    • Build Sheet: Ask for documentation detailing what was replaced, machined, and specs.
    • Rebuilder’s Reputation: Research online reviews and ask for references.

• Completeness:

  • Determine if you’re buying a short block, long block, or complete engine. A "complete" engine often means less hassle during installation as you won’t need to source intake, carburetor, distributor, etc. However, these add to the cost.

• History & Mileage (if known):

  • For used engines, understanding its prior life (e.g., from a well-maintained daily driver vs. a neglected farm truck) can offer clues about its condition. Mileage is less critical for rebuilt engines.

• Price:

  • Compare prices across different sellers and types of engines. Be realistic about what a quality rebuilt engine costs versus a cheap used core.

• Shipping & Logistics:

  • Engines are heavy! Factor in freight shipping costs, which can be substantial. Ensure the engine is properly crated and insured. Local pickup is always preferable if possible.

• Accessories:

  • Will it come with the necessary intake manifold, carburetor, distributor, exhaust manifolds, alternator, power steering pump, and brackets? Often, these are sold separately or need to be sourced from your old engine.

Installation and Maintenance Tips

Once you’ve acquired your AMC 360, consider the following for a smooth installation and long life:

• Professional vs. DIY: While the 360 is simpler than modern engines, installation can be complex. If you’re not experienced, consider professional installation.
• Supporting Systems: Ensure your vehicle’s transmission, cooling system (radiator, fan), fuel system (lines, pump, tank), and exhaust are compatible and in good condition to handle the new engine.
• Bell Housing & Motor Mounts: Verify compatibility with your existing transmission. AMC V8s use a unique bell housing bolt pattern.
• Carburetor Tuning: If running a carburetor, proper tuning is crucial for performance and fuel efficiency. This often requires some trial and error or a professional tune.
• Break-in Procedure: If you’ve purchased a rebuilt or new engine, follow the rebuilder’s break-in recommendations carefully. This is vital for piston ring seating and overall engine longevity.
• Regular Maintenance: Adhere to regular oil changes (using appropriate classic engine oil with ZDDP, or an additive), filter replacements, spark plug changes, and carburetor adjustments. Address any leaks or issues promptly.

Potential Challenges and Solutions

• Finding a Good Core: High-quality cores are becoming rarer. Be patient and cast a wide net.
• Year-Specific Variations: While generally similar, there can be minor variations in components (e.g., accessory mounts, intake manifold designs) depending on the year and vehicle. Research your specific application.
• Shipping Damage: Thoroughly inspect the engine upon delivery before signing off. Document any damage immediately.
• Troubleshooting: Classic engines can have quirks. Be prepared to troubleshoot vacuum leaks, carburetor issues, and ignition problems. A good service manual is invaluable.
