I just rebuilt a lsvtec turbo motor .. everything in the bottom end was redone and refreshen up .. the motor is all together . i just need help with timing .. I lined the crank up with the mark on the block for TDC .. Then lined the cams up for TDC they have ajustable cam gears on them AEM older style .. I put to pins in that hold the cams tight put my belt on .. Turned the motor over all 3 marks line up .. there are two that are stright and one with a circle.. i was just wondering if the timing was done right .. the motors in the car it has spark and cranks over but wont start ..
