BB Mopar Aluminum

BMP Hemi/Wedge Aluminum Engine Blocks ( Available Summer 2019 )
Bill Mitchell Products engineers have collaborated with leading Chrysler racers and developed a highly refined version of the original 426-style  block. It’s been designed using CAD/CAM 3D technology not available when the original was developed, and is manufactured to far more critical specifications. The BMP 426 Hemi features dual pattern Chrysler/GM bellhousings & more efficient lubrication. This is the ultimate block for Chrysler applications! Available in Hemispherical or Wedge configurations.
Due to the high demand we are taking orders with small deposits of $500.00 to reserve spot on the schedule.
