For more than 45 years, Bouchillon Performance Engineering has sold, serviced and manufactured Mopar parts with one thing in mind: the customer. Nothing is worse than calling a company that is just trying to sell you a part for your vehicle, with no knowledge or experience behind their sales drive. Our breadth of knowledge and experience sets us apart.

We specialize in Mopar Performance parts and service for all makes and models, from classic creations to modern muscle machines. Not only do we sell and service Mopar parts, we also custom manufacture many Mopar parts to make that custom job you are trying to build a reality.

JUST RELEASED Gen III Hemi to Torqueflite                                        Flexplate   

Many of you have been asking about the Torque Converter Drive Plates or Flexplates for the Gen III Hemi's that allow you to use the 727, 904, 500 or 518 Transmissions behind them. Many of you are aware of the poor designed piece that Mopar Performance originally released and has been copied by others that had the too large of holes for the torque converter bolts. The builder had to use some sort of spacers, or it would rattle and eventually crack.

There were other complaints about the older clover leaf style drive plate that would crack under stress and load. Click here for more details!
