Ep 21. 460 to the Max

In episode 21 of season 2 of PowerNation: Engine Power titled "460 to the Max," the hosts turn up the heat on their Ford 460 big block engine build. Starting with the bare block, they aim to create a high horsepower, naturally aspirated engine that can handle the demands of both street driving and the track.

The episode begins with the hosts discussing their plans for the engine, including using aftermarket parts to increase horsepower and reliability. They begin the build by installing a set of custom pistons, which will allow them to increase the engine's compression ratio. This will help the engine produce more power, especially at high RPMs.

Next, the hosts install a new camshaft, which will provide more lift and duration than the stock cam. This will improve the engine's breathing and allow it to produce more power at higher RPMs. They also install a set of high-performance rocker arms, which will improve the engine's valve train and allow it to rev higher.

As the build progresses, the hosts continue to install a variety of aftermarket parts, including a new intake manifold, carburetor, and exhaust system. They also make a number of modifications to the engine's cooling system, including installing a high-flow water pump and a larger radiator.

Throughout the episode, the hosts take the time to explain the various modifications they are making and how they will impact the engine's performance. They also offer tips and advice for viewers who may be looking to build their own high-performance engines.

As the build nears completion, the hosts fire up the engine for the first time and run it through a series of tests to see how it performs. They are pleased with the results, which include a significant increase in horsepower and torque compared to the stock engine.

In the end, the hosts are happy with the finished product and feel that they have built an engine that is both powerful and reliable. They encourage viewers to take on their own engine builds and to not be afraid to try new things and experiment with different combinations of parts.

Overall, "460 to the Max" is an informative and engaging episode of PowerNation: Engine Power that is sure to appeal to both car enthusiasts and gearheads alike. With its detailed explanation of engine build techniques and its focus on performance and reliability, it is a must-see for anyone interested in high-performance engines and automotive engineering.
