Hemi Engine Conversions Packages

America's Most Wanted 4x4 (AMW4x4) has perfected Jeep® HEMI® Conversion Packages. We start with genuine Mopar® crate engines and transmissions, adding AMW4x4 engineering and manufactured adapters, brackets and tubing kits. Our packages include everything that is needed, from the correct oil pan to the complete exhaust system and proprietary engine calibration. These are the most complete HEMI® Conversion Systems period! All conversions include a 3-year/36,000 on engine-conversion parts and 1 yr warranty on labor by approved licensed repair service centers when AMW4x4 installs the HEMI® Conversion Package.
