What You Should Know Before Buying A Crate Engine?

With so many options for crate engines out on the market, how can a person be sure they don’t buy some piece of junk and end up wasting money? Let’s review some simple things that are important considerations when purchasing a Chevy small block crate engine.

What Is Your Budget?

Deciding on a budget before searching for an engine is always good. Small block engines come in all shapes and sizes with different displacements and components. Remember, an engine installation sometimes goes in a direction other than people envision (there are always additional expenses for parts or labor for outside work that might be needed). The amount of money you spend for the engine is only a portion of what will be needed for an entire restoration project. Spend some time thinking about your budget, and go in armed to stick to those figures.

What Kind Of Engine Do I Need?

A crate engine can be a new or remanufactured powerplant, and this is often the biggest determiner of the price. Prices can vary greatly, but if a brand-new crate engine is going to bust your budget, consider purchasing a reconditioned or remanufactured motor. You want to double-check the warranty and be sure you purchase from a reputable source.

What Warranty Is Offered?

Many engine purveyors offer limited warranties on their engines, and you should familiarize yourself with the details. Should something happen and the engine fails, you want to have some recourse to help get some of your money back.

What Does The Dyno-Test Say?

A dyno test will help ensure your purchased engine meets its horsepower and torque values. Knowing whether your engine has been dyno-tested can help ensure the quality of the build and give you confidence as you place the engine into your project vehicle.

What Are The Most Popular Crate Engines?

There are lots of different small-block Chevy engines that can be purchased, but there are some that are more popular than others.

The 350 ci V8 engine (L48) was developed in the latter part of the sixties, first appearing in the 1967 Camaro SS. Over the production years (‘67-’80), the L48 would appear in almost every car that Chevrolet made, including the Camaro, Caprice, Chevelles, Novas, El Caminos, and the ‘75 - 80 Corvette. In addition, the 350 morphed into many variants, including the LT1 (1970 - 72 Corvette and Camaro Z28). Other popular versions are the LT1, L98, and L31 (5700 Vortec engine).
