Custom Rebuilt vs. Exchange Engine

  Why a Custom Built Engine
Is Your Smart Choice

Nobody welcomes the news that they need a new engine. However, this page will help you make an informed choice in selecting the right engine for your vehicle.

Rebuilding your engine is preferable to swapping it for an "assembly line built" or so-called "exchange" engine. A custom rebuilt engine provides many advantages including the use of the engine originally designed for your vehicle, the precision skill of a local craftsman utilizing quality parts, customizable to your special needs, and warranty protection superior to the typical assembly line exchange engine.

The following charts identify some of the significant differences between a custom rebuilt and an "exchange" engine. They compare both the overall product quality and warranty protection differences between the two different types of engines.

Take a moment to examine the differences and you will see why Scroggins Machine, Inc. recommends a custom rebuilt engine. We can rebuild most engines in 2-4 days.

Common Problem with Exchange Engines

A very common problem with exchange engines is the rebuilder "crack repairs" blocks and heads. This procedure is widely known to be substandard at best. Crack repairing is not recommended on a quality rebuild. Salvaging cracked engine and blocks saves the builder money, but as a result you are stuck with a inferior engine. Scroggins Machine, Inc. does not use crack repaired cores. Ask your rebuilder if they use crack repaired blocks or heads. If they say yes, call us.

Clearly the Best Choice

When you do your homework, you will see that a custom build engine is clearly your best choice. A quality product, rebuilt to exacting standards, using your original engine. A product that is second to none and one that ensures your complete satisfaction and peace of mind.
