ICT BILLET 551628 Details

These brackets allow a LS series engine to be bolted into a vehicle that originally had a small block chevy engine with your existing mounts (see photos).
 
  • Made with OEM specifications for the best possible fitment into your vehicle
  • These plates will move the crankshaft centerline up .17" in the vehicle 
  • Made in Wichita, Kansas from aerospace grade, USA produced, 3/8" billet aluminum
  • Includes: 2 adapter plates, 8 flat head bolts, and 6 flange M10-1.5 bolts (plates are M10 threaded, use the hardware included)
  • Natural aluminum finish
  • Will work with both SBC and BBC engines
 
There are 4 positions for maximum adjustment of engine; from .100" forward of OEM bellhousing position. Due to bolt interference, OEM location is not possible for any brand of flat style swap plates (forward position shown in most photos). Secondary positions are: .600", 1.86", and 2.36" engine moved forward.
 
These swap plates will shift the crankshaft centerline up .177" above factory small block location.
 
At ICT Billet we use GM factory specifications to determine exact mounting locations for the most accurate engine positioning.
 

Application

These LS engine conversion motor mount adapters create clearance interference with the OEM lower passenger side A/C compressor bracket. The factory bracket is not compatible in this configuration. Proper A/C fitment requires either a compressor relocation bracket or an aftermarket accessory drive system utilizing a smaller, short body A/C compressor.
