Ford vs. Chevy, Toyota vs. Honda, Cummins vs. Duramax, engine rivalries are alive and well and on display at the PRI Show. For three glorious days each December in Indianapolis, we celebrate all things motorsports-related, with some brand-loyalty banter mixed in for good measure.

Horsepower is the focal point at the PRI Show. Everywhere one looks, there is plenty of eye candy on display, built into the vast selection of race engines sprinkled throughout the aisles. We scoured the entire PRI Show to bring you 10 race engines that were built for use in midgets, drifting, drag racing, road racing, and more. From
a personal project to the quickest side-by-side, and even one engine that arrived in Indianapolis fresh off the dyno, this selection represents what makes the racing industry so great.
