V10 Viper engines are also a specialty with 20 years of proven experience in developing very powerful V10 Engines.

Ned Erkman started to develop the new high tech 5.7 and 6.1 Hemi engines 15 years ago by custom modifying the Hemi cylinder heads and by designing his won custom ground camshaft profiles that deliver superior performance.

In 2015 Tony Kurz contacted Ned  Erkman to build a 6.1 Hemi engine into a 426 Cubic Inch Displacement Hemi for a supercharger application and after this engine performed better than what was originally expected the new business Morepower Performance was established in 2018.
