Benefits of Crate Engine

  • Improve fuel mileage. The best crate engine will improve key engine components, making your vehicle run more smoothly and efficiently. This may also increase the fuel mileage of your vehicle, so you’ll spend more time on the road.
  • Increase in safety. Your car’s engine is one of the most essential parts of your vehicle. Making sure it is in the best shape will keep you safe on the road. Replacing a worn-out engine with a crate engine will lower the chances of any breakdowns.
  • Save money. Swapping out your engine is one way to save you cash. Driving on a faulty engine can lose you hundreds if not thousands of dollars on constant repairs. Replacing it with a crate engine will set you back one payment instead of several.

Types of Crate Engines

Remanufactured

A remanufactured crate engine is one that is sent back to the original manufacturer for repairs. The company removes all the malfunctioning parts and replaces them with a combination of new, reused, and repaired equipment to maximize the engine’s performance. The engine is designed to function as closely to the original engine specifications as possible. 

Rebuilt

A rebuilt crate engine is one that is completely gutted of worn-out, damaged, or old parts and constructed with brand new ones. This improves the overall performance and reliability of the engine. Every upgraded part is matched with the OEM ones to ensure every piece of equipment matches the previous parts.

Used

A used crate engine is pretty self-explanatory, as it has experienced a lot of use in other vehicles or been exposed to a lot of mileage. They are the best engine for anyone working on a budget; however, you do run the risk of it failing. 

New

A new crate engine has never been used, and you get to pick and choose the exact specifications and configurations you want. You know your vehicle best, so you get to select an engine that performs exactly as you need it to. The downside is that they will generally be more expensive and have higher insurance and tax rates.

Key Features

Compatibility

You’ll want to make sure the crate engine is compatible with your vehicle. If you are looking to outright replace the engine with a similar model, ensure it has the same number of cylinders and power. If you get one that is too large or robust, it may not fit your vehicle. 

Materials

To get the best-rated crate engine for your car, you’ll want to look for one that is made up of strong and durable components. After all, it is the most essential part of making sure your car runs, so it needs to have long-lasting components.

Horsepower

If you want to replace the engine to enhance its power and torque, consider finding one with a high amount of horsepower. While you can always increase this number later by adding other components, choosing more horsepower gives your ride an extra boost.

Other Considerations

  • Additional Parts: If you are doing a full engine swap, consider also changing out other engine components, such as the rotating assembly and head caskets, the camshaft, intake manifold, and the carburetor.

General Motors is well known for its creation of powerful vehicles, and its small-block crate engine design is no joke as a racing engine. This aggressive LS3 6.2L engine comes with an impressive 525 horsepower. That amount of power also gives you up to 6,200 rpm with 486 pounds of torque at 5,200 rpm.

Best Crate Engine Honorable Mention: Genuine GM Economy Performance Engine

This small-block V8 crate engine is packed with a high amount of power and torque to get your car where it needs to go. It puts out around 290 horsepower and up to 332 torque when the pedal hits the metal. You also get a Camshaft lift at .450 intake and .460 exhaust plus a Camshaft duration at 050 at 222 degrees intake and exhaust.

All that horsepower adds up to a whopping total of 5,100 rpm, while the torque gives you 3,750 rpm.

However, it can be a pain to install. You may end up having to make some modifications to your vehicle to properly fit it inside and get it running. These can include replacing the manifolds or headers, but it can vary on the vehicle itself. It is also on the more expensive side, but that has to do with the V8 style and a large amount of horsepower.

Tips

  • Make sure you have the proper tools and equipment to install a crate engine. You will need an engine hoist to properly and effectively load it into the engine compartment.
  • Crate engines are fully assembled but many, like long blocks, may not come with internal components, such as a fuel system, electrical system, an intake, or exhaust system. However, you can find several engines with a carburetor, plugs, plug wires, a distributor, air intake, harmonic balancer, fan, starter, wiring harness, exhaust manifold, water pump, and an alternator.
  • If you are replacing a small block engine with a big block crate engine, you may have to make modifications for it to fit. This can be anything from replacing the stock frame to cutting the inner fender and shock towers.

Q: How do I install a replacement crate engine?

A: While crate engines are designed to be somewhat simple to install, they can be difficult if you aren’t familiar with them. The best way to make sure everything is installed properly is to check with the manufacturer. They should have a guide on how to replace and swap out a specific engine.

Q: Do I need to replace everything connected to the engine?
