Dart Machinery was tasked with creating an engine for the project. The result is an 8.4-liter Chevrolet engine with Dart Pro2 cylinder heads and the Big M 540 short-block package. While that’s very appropriate for a monster truck, Jurassic Attack is a different story due to its hydrogen combustion system. It operates like a traditional combustion engine, unlike the fuel-cell setup in the Toyota Mirai.
A standard fuel delivery system wouldn’t cut it, so the team had to look elsewhere for assistance. Phinia, a spin-off of Borg-Warner, was tasked with creating special hydrogen M3.5 PFI H2 injectors for the monster truck, allowing fuel to flow to the mighty engine. Phinia’s Chief Technology Officer and Vice President, Todd Anderson, commented that seeing the company’s technology in a race engine is excellent.
Other modifications include Total Seal AP piston rings that reduce emissions and maximize power. Several big brands contributed to the build, including Edelbrock and Haltech.
