If i put a Cheetah in a motor vs a stock cam +.100 lift could i see the difference with a dial indicator on the pushrod? I CAN NOT get into the motor. I'm asking for a tech situation. Just want to see if the lift is that much different in the dark in a dusty tech shed.I AM NOT SURE WHAT YOU ARE GETTING AT? ARE YOU SAYING YOU CANNOT PULL OFF THE ROCKER COVER BECAUSE IF YOU CAN'T THATS GOING TO BE A TRICK! IF YOU CAN PULL THE ROCKER COVER USE THE DIAL CALIPERS LIKE A HEIGHT GAGE FROM THE RETAINER TO THE HEAD FOR TOTAL LIFT OR THE ROCKER, ON THE PUSHROD SIDE, TO THE HEAD FOR CAM LIFT. IF I READ YOUR QUESTION CORRECT THE ANSWER YES! O-YA AND USE A GOOD FLASHLIGHT!
