Crate Engine Guide

Crate engines are a great choice for most people performance enthusiasts. Buying a crate motor from a reputable company like GM Performance Parts gives you a few things you just can't get when you buy your own. First, you never know exactly what you're going to get on the dyno when you choose components and build up an engine. There may be some trial and error, which costs money. You can copy another engine build, but that's essentially like buying a crate engine. One of the advantages of a crate motor is knowing that the company chose the internal engine components and dyno tested the engine to show you a dyno chart with horsepower and torque numbers as they relate to RPM.

Another advantage to a crate motor is the warranty of the more reliable engine builders. You can't get that with your own build. Of course, the reason a good warranty is offered is usually because quality parts are being used and good engine building techniques are adhered to.

What to Look For In A Crate Engine

You have to know what you want to do with the engine. Is it an everyday cruiser that needs moderate horsepower or are you going to trailer your car to the track and terrorize the drag strip? Crate engines are purpose built. Internal engine parts need to be strong enough to withstand the abuse you're going to give it. Look for forged pistons and a forged crankshaft in an engine that will be run hard.

    Other Notable Choices to Make
  • Cast iron heads are less expensive, but weigh much more. Even worse, that weight is over the front where you don't usually want the weight for drag racing.
  • High compression engines also generally require higher octane fuel, costing you more at the pump.
  • An engine builder's reputation is often well known. Check on-line to see what people say about a certain engine manufacturer.
  • Cost is on most people's mind. Be realistic about your needs. A low end motor is not going to stand up to daily abuse.
