Had same issue with OEM stock engine. After trying Oxy Acety & strong impact had to move on.
Found a 19mm 3/4" drive impact socket (thick black) at Northern Tool. Linked it with massive 3/4" drive breaker bar & probably 6-8' pipe extension. Secured flywheel with an attached beefy long square metal tube angled down to deck (eng mounted in engine stand). That ended all the trouble... came loose with a SNAP & threaded off easy rest of way. CRAZY!
Good Luck

I'm gonna take the oil pan off, let it sit on the floor, have someone heavy (brother) stand on the engine, while I take it off with the breaker bar + cheater pipe.
and oh, I'm getting that Oxy/Acy torch tomorrow morning.
Yup had same problem with mine soaked with all kinds of penetrating oil all kinds of impacts all kinds of heat for like 2 weeks of evenings... Finally had brother in law stand on engine while I used breaker bar plus 6ft pipe from floor jack snapped loose the came off rest of way with fingers... Had to replace mangled bolt but e shaft was fine
Penetrating oil will do nothing for you. It's a long bolt slathered in Loctite.
Normally, I heat the bolt up with a propane torch to get the Loctite hot. Lock the flywheel in place (I have a tool that locks the ring gear) and put a breaker bar and a BIG damn pipe on it.
You can also bolt a chain to the rear housing then bolt the other end of the chain to the flywheel. Use a disposable bolt, the bolt can get bent.
Impact never works for me. You need that twisting, not hammering, force to overcome the Loctite.
Also helps to have the engine on a proper engine stand so it isn't trying to walk across your garage floor.
Funny thing is people always get excited about the flywheel nut. I'll happily take off flywheel nuts, that front pulley bolt is where boys become men.

it will probably easier to just put the engine back on the floor and start from there. (flat surface)
but I'm gonna try the oxy acetylene torch first, burn baby burn !
I did, replied, thx for the idea !

I've ran into this issue a few time . I was able to use map gas but I had to literally sit there heating it up for about half an hour while the heat penetrated through . Oxy / acetylene is definitely quicker but be careful not to melt the bolt lol I did that once too luckily it was just the center of it. I also used a 1/2 drive ratchet that I swear is indestructible and smack the **** out of it with what I believe is a 3lb hammer might be 5 but breaks free just about every time .

Get a 3/4" craftsman wrench you don't care about, and a BFH. Be sure to lock the flywheel first (duh).
I used a MAPP torch and got things to glow. Then I beat on the wrench unmercifully. The bolt eventually moved after several full strength hits.
I had to do this twice. Good thing most FD engines have a long headed 19mm bolt.
