Gen3 Performance Parts Aluminum VVT-Designed HEMI Bare Block - Water Version 2022


This G3PP aluminum block is designed for use in builds up to 1,800 BHP. Not only is this G3PP block stronger than the factory Hellcat, "BGE" and Demon/RedEye engine block, it also offers huge weight savings, too. This G3PP block is almost 80lbs lighter than the OEM cast iron block



Block Applications: The G3PP aluminum blocks are designed to be a direct replacement for the Hellcat and 6.4L Gen3 VVT HEMI applications. This block will also fit other 5.7L and 6.1L applications but will possibly need additional parts due to deck height and front cover/camshaft differences.
