I imagine it will be easier to do if you get 2 steel bars about 18" long that are a snug fit into the main cap bolt holes. They should extend almost all the way through the cap. Put them in the cap and wotk it back and forth with the crank resting on the cap. It should loosen up. Don't get brutal and let the bars slip out, you can crack the cap at the outer end.

I give it a try, to the grinder

Remember, this is what we in the business call "fun".

I was doing a search of this site on an unrelated item and found a post stating that there are two bolts hidden behind the flywheel.

 

[red devils dude]

your kidding me, that's not in any of the manuals O man I hope not if there in there I'm in trouble.

Is there any jacking bolt holes???

 

[red devils dude]

jacking bolt holes?
what are they.

 

[red devils dude]

hey guys take a close look a the diagram there are two small holes in the back of the #7 main bearing cap.
jasonS may be right if he is I'm in trouble.

Jacking bolt holes are threaded holes that go all the way through. So when you screw a bolt in them, The end of the bolt touches what's underneath. As you turn the bolt the part is jacked out of it's position.
In your diagram part#2 (main cap) has two holes (not the orignal bolt holes) on the top, or bottom if your under the truck. Are those holes threaded? They may be larger for relief before the threads start. If so i'll bet you use bolts to jack the main cap out of the block.

Can you take a flashlight between the block and the flywheel to see if there is bolts there? I can't see a reason that they would be there. The main cap should have grooves to line up in the block.
