The short answer is: it depends. While many crate engines are indeed brand new, built from the ground up with all-new components, the term “crate engine” also encompasses remanufactured or rebuilt engines. The key is to understand the specific type of crate engine you’re considering. A true “new” crate engine will be pristine, unused, and come with the expectation of a full lifespan ahead. Rebuilt or remanufactured crate engines offer a more budget-friendly option, but with some caveats. So, let’s delve deeper into this engine enigma and explore the fascinating world of crate motors.
Understanding the Nuances of Crate Engines
Crate engines have become increasingly popular for car enthusiasts, restorers, and anyone looking to breathe new life into their vehicle. The name itself is derived from the fact that these engines are typically shipped in, well, a crate! But beyond the packaging, understanding what you’re actually getting is crucial.
The primary appeal of a crate engine is convenience. You receive a fully assembled engine, ready to be installed, saving you the time and hassle of sourcing individual parts and building the engine yourself. This is especially attractive for complex engine builds or when replacing a severely damaged engine.
New vs. Remanufactured: The Core Difference
The most important distinction lies between a new crate engine and a remanufactured (or rebuilt) crate engine.
New Crate Engines
These are exactly what they sound like: completely new engines, assembled from new parts. They’re typically produced by the original manufacturer (like Chevrolet Performance, Ford Performance, or Mopar) or by reputable aftermarket companies. You can expect the same performance and reliability as a factory-installed engine in a new car. They offer peace of mind, knowing every component is fresh and untarnished.
Remanufactured Crate Engines
Remanufactured engines (sometimes called rebuilt engines) are previously used engines that have been thoroughly inspected, cleaned, and refurbished. Parts that are worn or damaged are replaced, while other parts are reconditioned to meet factory specifications. These engines often offer a more affordable alternative to new crate engines and can still provide good performance and reliability if the remanufacturing process is done properly.
Factors to Consider When Choosing a Crate Engine
Selecting the right crate engine involves careful consideration of several factors:
- Budget: New crate engines are generally more expensive than remanufactured ones. Determine how much you’re willing to spend.
- Application: What are you planning to use the engine for? A daily driver will have different requirements than a high-performance race car.
- Performance Goals: Are you looking for increased horsepower and torque? Or simply a reliable replacement for your old engine?
- Warranty: Pay close attention to the warranty offered with the engine. A strong warranty provides peace of mind and protection against potential issues.
- Reputation of the Manufacturer: Choose a reputable manufacturer or supplier with a proven track record of quality and reliability.
Identifying Key Components Included
Depending on the specific crate engine, the included components can vary. Some crate engines are “long blocks,” which include the engine block, cylinder heads, and internal components. Others are “short blocks,” which only include the engine block and rotating assembly (crankshaft, pistons, and connecting rods). Still others are “turn-key” engines, which are fully assembled and ready to run, complete with intake manifold, carburetor (or fuel injection system), ignition system, and exhaust manifolds. Carefully review the engine’s specifications to understand exactly what’s included and what you’ll need to purchase separately.
FAQs: Demystifying the World of Crate Engines
Here are some frequently asked questions to further clarify the intricacies of crate engines:
1. Is a crate engine a complete engine?
It depends on the type. A “turn-key” crate engine is the most complete, usually including everything needed to run. Long blocks and short blocks require additional components.
2. Will a remanufactured engine last as long as a new engine?
Possibly, but not guaranteed. The longevity of a remanufactured engine depends on the quality of the remanufacturing process, the parts used, and proper maintenance.
3. Are crate engines reliable?
Yes, especially those from reputable manufacturers. However, reliability also depends on proper installation and maintenance.
4. Does a rebuilt engine have 0 miles?
Yes, on the engine itself. But the rest of the car retains its original mileage and wear.
5. Are crate engines ready to run?
“Ready-to-run” or “turn-key” crate engines are ready to run after installation. Other types require additional assembly and component sourcing.
6. Do crate engines come with spark plugs?
Turn-key crate engines often include spark plugs. Check the engine’s specifications to be sure.
7. Do crate engines come with an ECU?
Some performance crate engines include an ECU (Engine Control Unit), especially those designed for fuel injection. Standard replacement engines may not.
8. Is a new motor the same as a new engine?
Technically, no. Motors run on electricity, while engines run on combustion. However, the terms are often used interchangeably in casual conversation.
9. Why buy a crate engine?
Crate engines offer a convenient and often cost-effective way to replace or upgrade an engine. They provide a known quantity in terms of performance and reliability.
10. How much horsepower is a 350 crate motor?
It varies greatly. A basic 350 crate engine might produce around 290 horsepower, while a high-performance version could generate significantly more.
11. Are crate engines remanufactured?
Some crate engines are remanufactured, while others are entirely new. Always check the engine’s specifications.
12. Is it cheaper to buy a crate engine or build one from scratch?
Often, buying a crate engine is more affordable and convenient than building an engine from scratch, especially considering the cost of individual parts and machining.
13. Are cars with replaced engines reliable?
Yes, assuming the replacement engine is properly installed and maintained. A newer engine can improve the car’s long-term reliability.
14. Are Chevy crate engines street legal?
Some Chevy crate engines are street legal, particularly those with CARB (California Air Resources Board) E.O. numbers. Check the engine’s specifications for compliance.
15. How many miles will a crate engine last?
A properly maintained new crate engine should last for many years and miles, potentially exceeding 200,000 miles or more. A remanufactured engine’s lifespan depends on the quality of the remanufacturing process.
Making the Right Choice
Ultimately, the decision of whether to choose a new or remanufactured crate engine depends on your individual needs and budget. Carefully evaluate your options, research different manufacturers and suppliers, and consider your long-term goals for your vehicle.
