you are talking about the harmonic balancer and crank bolt?
1. get a breaker bar and socket and rest the breaker bar on CONCRETE of the RIGHT side of the engine if you give it a small kick with the starter the rotational force should loosen the bolt.
2. rattle gun is best as it avoids twisting the crankshaft
3. if you have two people you could use a lever bar on the flywheel against the bellhouseing to hold the crank and the other to undo it.
4. if your clutch is good enough, you could put it into gear and have someone put thier foot hard on the brakes which is just as effective as holding the flywheel if done properly.
the harmonic balancer can be a bitch to get off,
two lever bars on either side of the balancer and edge it off if its not mega stuckfast... be careful of the timing case cover..
use a balancer puller is the easiest and safest way to get it off
let us all know how you go
