When using a stock crank sensor and holder on a stock front cover has anyone seen the ref angle (10 Deg)on FAST be way off using a Buick MotorSports hub? Im going to check a friends car because he never set his and left it at 10d deg..The car has never run right and i told him id set it for him and see if the timing is off. Stage 2 on center block,3.65 crank,big roller cam,160# injectors,Fast,76 gtq turbo,S2 heads,turbo 400,3000# car.The car runs around the 140 MPH range with 25.5 deg timing and 26# boost
