This universal ICT Billet adapter plate set is produced in the U.S. from 3\/8\" aerospace-grade billet aluminum to OEM specifications, shifts the crankshaft centerline up by .17\", and includes the necessary bolts for a straightforward installation.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this adapter maintain correct engine alignment?\u003c\/h3\u003e\n\u003cp\u003eThe ICT Billet plate raises the engine position relative to the chassis by a precise .17\", bringing the LS crank centerline into correct relation with SBC transmissions and drive components.
