The 15 Best Crate Engines You Can Buy

Jun 7, 2021

Category: Rides

When setting out to build a project car, there’s an absolutely enormous variety of makes, models, and eras to utilize as a donor vehicle. And while a great many of the models from decade’s past undeniably boast markedly more character and personality than modern late-model offerings, they tend to be powered by relatively antiquated, underpowered, unreliable engines. One readily available solution to this problem is standalone new production motors, commonly referred to as “Crate Engines.”

No matter what build genre or style, there will be a wide variety of compatible crate engines available, from existing powertrains plucked directly from production car models to high-performance forced-induction mills. With the popularity of automotive projects continuing to grow, automotive manufacturers have responded with an ever-more-impressive array of ready-to-go lumps. And while there’s admittedly no shortage of truly solid a la carte motors to choose from, there are an elite few that stand out from the crowd due to either their incredible performance capabilities and power output, versatility, or value.

Looking Under The Hood

The Qualities To Consider When Buying A New Crate Motor

Even the more primitive engines that exist are still incredibly complex machines, and as such, there’s an extensive number of factors to take into consideration when shopping around for a crate motor. Without venturing too far into the weeds, we’ve compiled this condensed list of seven of the most important elements to take into account before making your purchase.

Engine Size & Configuration: Measured by displacement in cubic inches or liters, an engine’s size is one of the more important factors in determining its power and performance. Likewise, the type of engine configuration being utilized will also play an equally pivotal role in an engine’s overall abilities. If you’re largely unfamiliar with the specific traits and characteristics of the different available engine types, this is an area well worth looking further into, as different setups — such as V-layouts versus inline configurations — will offer different strengths and weakness, making them more conducive to some projects than others based on factors such as power delivery.

Aspiration & Fuel Delivery: Another incredibly important factor in calculating an engine’s power output is how said engine is aspirated. Powertrains that have been fitted with forced induction systems (i.e. superchargers or turbochargers) are capable of punching well above their weight in terms of power output relative to their displacement. Unsurprisingly these systems don’t come cheap, though they undeniably hugely bolster performance. We’d also recommend opting for a fuel-injected crate motor as they’re markedly more efficient and will save you the headache of having to perform routine carb work.

Horsepower & Torque Output: A vehicle’s size, power delivery, and running gear will all play crucial roles in determining performance, though no other metrics will give you a better sense as to an engine’s raw abilities than horsepower and torque output. On top of an engine’s outright oomph, it’s also worth exploring at what point in the rev-range an engine’s (peak) power kicks in. And, with power output being such a central focal/selling point of engines, manufacturers have been producing mills with some wildly impressive power figures right out of the box.

Physical Dimensions: In what will probably come as a shock to absolutely no one, the size of the crate engine you can use will be dictated by the available real estate in your donor car’s engine bay. For this reason, it’s wildly important to double-check the physical dimensions of both the crate engine and the engine bay, while being sure to factor in other parts such as the transmission, cooling system, intake and exhaust, and so on.

Conduciveness To Tuning: Many of today’s production crate engines already put down genuinely impressive horsepower and torque figures, though if you’re interested in squeezing out a bit more muscle you should definitely consider a crate motor that lends itself to massaging and tuning, as some crate engines are much more conducive to performance upgrades than others. What’s more, there are also third-party companies that produce pre-tuned high-performance and race-spec turn-key crate engines.

Fuel Type: Though the vast majority of today’s crate engines can comfortably run on pump-fuel, there are some more high-performance powerplants that sip on higher-octane race fuels, which are not only substantially more difficult to source, but also come at a much steeper price, with 110-113 octanes typically costing around $10 – $20 per gallon.

Additional & Unforeseen Costs: When making a budget to build a project car, it’s important to consider all of the costs involved. When it comes to crate engines, this not only means the MSRP of the crated motor, but also tax and shipping costs, and money for installation — as well as cash set aside to purchase any parts that weren’t included with the engine such as intakes, disturbers, spark plugs and wires, thermostat and housing, alternator, wiring harness, and everything else needed to get up and running. While on the subject, it’s also worth pointing out that some manufacturers do sell complete turnkey engines with everything need to put together a running motor, plus there are combo bundles with grouped together items such as a crate engine and a controller pack.

Ford 306 Windsor-Block

Developed by Ford’s team of race engineers, the 306 Small Block engine is an extremely capable motor offered at an unbeatable price. Its immense popularity has also resulted in a massive aftermarket sector for the engine. And, while no longer offered directly through Ford Performance, these Small Block mills are still readily available brand new from a variety of parts dealers and online retailers.
