• Hydraulic Camshaft: A hydraulic camshaft with specifications of 224/230 duration at 0.050 lift and 0.477/0.480 lift provides a strong mid-range powerband, ideal for street performance.
• Hydraulic Lifters: Complementing the camshaft for smooth and reliable valve operation.
• Rocker Arms and Shafts: Essential components for the valvetrain.
• Edelbrock Aluminum Cylinder Heads: Lightweight and efficient aluminum heads that significantly improve airflow, contributing to the engine's horsepower and torque figures.
• Harmonic Balancer: Crucial for dampening crankshaft vibrations and protecting the engine.
• Edelbrock Air Gap Intake Manifold: A performance intake manifold designed to improve airflow and power delivery.

Assembly and Testing: Ready to Run

Crucially, this engine is advertised as Completely Assembled and Live Run Tested. This means it has been built, fired up, and run on a test stand to verify proper operation, oil pressure, and leak-free performance before it reaches your doorstep. This testing provides significant peace of mind.

Optional Upgrades: Customising Your Powerplant

The base price of $10,850.00 is just the starting point. Several optional upgrades are available to tailor the engine to your specific needs:

These options allow you to add essential accessories like power steering and air conditioning, or upgrade to modern electronic fuel injection for improved drivability and efficiency. The inclusion of a flywheel option caters to those preferring a manual transmission.

Core Deposits: Understanding the Process

A common practice in the automotive industry, particularly with engine and transmission sales, is the use of a core deposit. This system is designed to keep prices lower by encouraging the return of your old, rebuildable unit. Here's how it typically works:

What is a Core Deposit?

The core deposit is an amount added to your purchase price at the time of sale. This deposit is refunded to you once you return your old engine (the "core") in a rebuildable condition. The recycled metals and components from your old engine help offset manufacturing costs, allowing sellers to offer more competitive pricing.

How is the Core Deposit Charged?

The core deposit is added to your total at the point of purchase. You will receive an instant receipt detailing this charge. The deposit is held until your returned core is received and processed by the seller.

How Long Do I Have to Return My Core?

To receive a full deposit refund, your core generally must be received by the seller within 30 days of your original purchase date. Late returns may be subject to late fees, and any extensions typically require approval from a sales manager.

Refund Timeframe

Once your core is received and inspected, refunds are typically processed within 1-3 weeks. If you paid by credit card, the refund will be credited back to your card. For check payments, a refund check will be mailed. It's advisable to call and verify if you haven't received your refund within the expected timeframe.

How Do I Return the Core?

Most sellers will include a shipping form, often called a "Bill of Lading," with your new engine. You can arrange for the delivery driver to take your old core back upon delivery, or you can schedule a separate pickup by contacting the shipping company directly. Ensure you use the provided shipping forms to avoid personal billing from the carrier.

What if My Core is Bad or Missing?

If you don't have a core to exchange, the deposit amount will usually be added to your purchase price. In this scenario, you might also be responsible for a one-way shipping fee for the new unit. In cases of exceptionally low stock for a particular core, sellers may charge a higher price for the core when no exchange is provided. In rare instances of critically low core stock, a seller might reserve the right to not sell a product without a core exchange.

Can I Send My Core First?

For certain large components like engines, manual transmissions, and transfer cases, some sellers may allow you to send your core back before they ship your new unit. While this process can extend overall delivery times, it means you won't have to pay the core deposit upfront, only the price of the part and the shipping costs.

Excessive Damage to the Core

A core must be in a buildable condition to qualify for a full deposit refund. If your old engine has suffered catastrophic damage, it might not be accepted for a full refund. Always contact the seller if you have questions about the acceptable condition of your core.

Is a 318 a Good Engine?

The Mopar 318 is widely considered a very good engine, especially for its era and displacement. Its strengths include:

• Reliability: Known for its robust construction and ability to withstand regular use.
• Versatility: Suitable for a broad range of applications, from daily drivers to performance builds.
• Modifiability: Responds well to modifications, allowing for significant power increases with upgrades like those detailed in this performance build.
• Compact Size: For a V8, it's relatively compact, making it easier to fit into various chassis.
• Fuel Efficiency (relative): Compared to larger displacement V8s of the same era, the 318 could offer slightly better fuel economy when tuned correctly.

While a stock 318 might not offer earth-shattering performance by today's standards, a well-built and modified 318, like the one described, can be a potent and enjoyable powerplant. The 350 horsepower and 400 lb-ft of torque from this rebuilt unit certainly place it in the "good" category and beyond.

Additional Considerations

When purchasing a performance engine, always consider:

• Compatibility: Ensure the engine's bolt patterns and transmission compatibility match your vehicle.
• Warranty: Inquire about any warranty offered on the rebuilt engine.
• Shipping: Factor in the cost and logistics of shipping a heavy item like an engine. The package and crate option mentioned is often included at no extra charge, which is a good value.
• Payment: Secure payment methods, like the one mentioned (Engine Factory's secure payment merchant account), are essential.
