R5P7 368ci Engine

Mopar Small Block: 368ci R5P7 steel block race engine. The engine was professionally built by Harshman Racing Engines and Brett Miller. The Ritter Ritter R5 steel block was bought new in January 2019. We built this engine for a dirt modified. The engine tuned on the tame side for our application. It currently makes 755hp 560lbs tq. There’s plenty more HP to be had with some dyno tuning. This is a wet sump engine that utilizes a single stage external oil pump.
