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. 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. 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.

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. 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. Unsurprisingly these systems don’t come cheap, though they undeniably hugely bolster performance. superchargers or turbochargers) are capable of punching well above their weight in terms of power output relative to their displacement. Powertrains that have been fitted with forced induction systems (i.e. 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.Īspiration & Fuel Delivery: Another incredibly important factor in calculating an engine’s power output is how said engine is aspirated. Likewise, the type of engine configuration being utilized will also play an equally pivotal role in an engine’s overall abilities. 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.Įngine 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. The Qualities To Consider When Buying A New Crate MotorĮven 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.

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.

With the popularity of automotive projects continuing to grow, automotive manufacturers have responded with an ever-more-impressive array of ready-to-go lumps. 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. One readily available solution to this problem is standalone new production motors, commonly referred to as “Crate Engines.” 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. 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.
