Introduction

In this article, we will be comparing the size, weight, and horsepower per pound of different engines. We previously did a video where we compared a $9,999 Coyote engine to a $9,999 LS3 engine, but we forgot to measure and compare their physical dimensions. So, we decided to bring out all the engines we have in the shop and measure them. We have three engines to look at – the LSX 376, the Motown build from World products, and the Coyote engine. These engines are all unique in their own way, and it’s interesting to see the differences between them.

Engine Measurements

Let’s start with the Coyote engine. We measured the width of the valve cover, and it came out to a little over 29 inches. To get a height measurement, we measured from the crank centerline to the top of the boss 302 manifold, and it measured about 20.5 inches.

Next, we measured the Motown build from World products. This small-block Chevy engine measured around 23 inches in width and 22 inches from the crank center to the top of the crank bolt.

Finally, we measured the LSX 376 engine, which is a hybrid between an LS and a small-block Chevy. It measured approximately 23.75 inches across the valve covers and 20.25 inches from the crank center to the top of the Vitek throttle body.

Engine Weight

To measure the weight of the engines, we enlisted the help of Tim. Keep in mind that this is not an exact apples-to-apples comparison, as some engines may have additional components. However, it still gives us a general idea of the weight differences.

The Coyote engine, our only all-aluminum engine in this comparison, weighed in at 430 pounds.

The Motown build weighed 475 pounds, and the LSX 376 engine weighed a hefty 590 pounds.

Horsepower Per Pound

Now let’s calculate the horsepower per pound for each engine.

The Coyote engine produced 510 horsepower and weighed 430 pounds. This works out to be approximately 1.24 horsepower per pound, after accounting for the weight of the flywheel.

The Motown build, with its 682 horsepower and 475-pound weight, had a surprising output of 1.43 horsepower per pound. It was unexpectedly powerful for its weight.

Lastly, the LSX 376 engine, with its massive 1,079 horsepower and 590-pound weight, had an impressive output of 1.82 horsepower per pound. Despite being heavy, it delivered an enormous amount of power relative to its weight.

Conclusion

In conclusion, we have compared the size, weight, and horsepower per pound of three different engines – the Coyote, the Motown build, and the LSX 376. Each engine has its own unique characteristics and power output. The Coyote engine proved to be the lightest, but still packed a punch with its horsepower per pound ratio. The Motown build surprised us with its high horsepower per pound output, despite being an iron block engine. Finally, the LSX 376 engine, although heavy, delivered an exceptional amount of power relative to its weight.
