Spray it with some penetrating oil and use an impact if you have one. If not, you should be able to put the car in gear and use a breaker bar and extension to loosen the nut. if your still having issues after trying both of these technics. Use a strap wrench and hold the pulley. Don't worry some times you have to use force to get things apart. That's a stout part. Nothing will break!

The crank pulley bolts are nothing compared to the balancer bolt in the center, wait till you try to crack that one loose.
For the 4 pulley bolts hit em with some penetrating lube and let em soak over night if ya have to. Impact should work fine on the pulley bolts, but I doubt youll get the balancer bolt loose with one, Ive had to use a breaker with a 3' pipe over the handle for more leverage to brake those loose. Last one I did , even the parking brake and transmission in gear wasnt enough to stop the engine from rotating, instead the hole car was moving. So I used a small length of chain with a hook on one end , bolted one end onto where the pulley bolts to then the other end I hooked onto someplace solid in order to keep the engine still, even with the 3' pipe on my breaker it took all I had to get it loose.
Youll need a large breaker bar, and most likely a long helper pipe over to break it loose, and youll have to give it all you got. Penetrating lube wont help ya on the crank bolt, its sheer force for that one.

then you need to go buy a real impact instead of using a vatozone great neck one...lol my mac impact never flinches on the 302 crank bolts and it's broken loose 100's over the years.
