Get the 3.5' or 4' pipe off your floor jack, a breaker bar (not ratchet) and the socket. Put the breaker bar and socket setup on the crank pulley. Take the pipe setup off your floorjack and then slide it over the breaker bar. Then start to break it loose byy applying your force. *Make sure the rear wheels are on the ground and the tranny is in 1st gear.
Once you start to apply force to the 4' lever, it will begin to flex a little with some rebound ( the rubber section in the flywheel is doing this). Keep pushing or pulling(depending on how you positioned yourself with the car) with this untill you break it loose . You will prolly have to attempt this around 4 times until some the force in the torqued bolt is released. You will know when it breaks loose. You will end up applying at least a 60lbs of force if you are using the 4' pipe setup.
Oh, you better have some back muscles for rowing cuz you will be definately using them.
I did this and Its not easy but without a doubt possilbe without using an impact, SST tool or the starter trick. This is where the moment about the system will shine (For all you mechanical engineers).
