Probably a dumb question for the more avid mechanic but I'm in the process of pinning the crankshaft per Roe's recommendation prior to installing the SC. I have a 1 1/4" 3/4 socket, breakover and cheater bars but I can't seem to break the bolt loose. I have the car in gear (reverse) and the parking brake on but it feels like the motor is still turning when I try to torque the bolt loose. I'm afraid to go any further until I'm assured I'm not doing anything to screw anything up. Will the motor finally reach a stopping point if I continue and finally allow me to torque the bolt off? Also, when getting ready to rotate the crank to better position it to drill the other hole for the pins, I assume all I need to do is remove the spark plugs and put the car in neutral with the parking brakes set, then rotate the crank by putting the center bolt back in? Thanks for any input
