Powerboater Motor: Watch This Interesting 540ci Blown Big Block Get Built To Ocean Going Specs

As we always talk about around here, engines are built not just for raw power but they are built to suit their specific applications. This video serves as a perfect example of that as we’re going to watch a supercharged 540ci Chevy big block get built to power a big, bad ass, off-shore style power boat. The engine is unique in the sense that it uses a low profile supercharger, requires only lower octane pump gas, and is really designed to make near constant power at RPM levels where most engines are barely getting warmed up.

The constructions methods of the engine are similar to what anyone would see in a professionally built engine but with a few twists that are showed off and explained clearly through the video.

We love the fact that like all HP Monster episodes, this one is thorough and from the parts list to stuff like the unique valve covers used to allow access with the tight fitting manifolds, everything is explained and laid out.

Building marine engines is not about setting the world horsepower record but is it about getting the most out of the combo and making sure everyone is going to make it back to the dock under power.
