Proper engine mounting is a fundamental requirement of performing any LS engine swap and Hooker BlackHeart now makes it possible to accomplish this task in any GM 4th-gen F-body without having to swap out the stock V6 or LT1/LT4 engine K-member for a factory or aftermarket LS K-member. These brackets are designed for bolt-in installation onto the existing V6 (3.4L or 3.8L) or LT1/LT4 engine cradles. LS Oil Pan 302-2 can be used with these mounts


  • CAD designed for optimized strength and fitment
  • Provides same-as-factory LS engine and transmission location and inclination angle
  • Specific mounting brackets for 3.4L/3.8L V6 cars

  • Fabricated steel construction provides high strength at an affordable price
  • Compatible with stock GM or aftermarket rubber or polyurethane 4th-gen F-body LS engine mounts
  • Bracket-to-frame hardware included
