I tried:

ATF

PB Blast

Acetone

Mixtures of the above.

The BFH shown at full swing didn't move it.

It might be stuck.

Have you thought about drilling successively larger holes in the piston? I mean, obviously this would ruin the piston, but the block might be savable if you can take enough stress off of the piston to get it out. You'd need hole-saw type holes.

I'd be inclined to try rattling it with an air hammer before drilling holes in things. The sharp repetitive beating often helps when things are corroded together.

I agree, but I also think an air hammer is going to ruin the piston anyway.

Have you considered patenting whatever is holding this sucker in place?

Chunk of metal/hardwood on top of piston to protect it?

Metal might spread it out enough, but probably still damage it at the levels of impactitude which this seems to require.

Wood would just absorb the impact.

I think drilling is going to be the most direct route, but I don't understand if we need to keep the piston in one piece or not.

I'm thinking less force, more shock, here. I don't think we NEED to keep the piston though, just want to.

Some sort of acid soak that won't significantly attack the aluminum is still sticking in my head.

Have you tried throwing it on a bonfire yet?

Bonfire seems like overkill, I think a HF flamethrower torch bringing it to 350 or so (use laser thermometer), then hit it would probably do the trick.

But a bonfire is more fun. And I want to see the pictures.

Took a little bit, but finally have the Bellhousing from the 46 228 mounted to the 53 270. Hope to be able to get the clutch components assembled this week and have an engine back in the ol' truck

Test fit the 270 back into the truck last night. Baby steps.

So Shiney.

Got a few minutes On the garage today. Finally got the transmission reattached. Slow progress, but not stopped

Edit: for pic. love that the floor comes out for this job. Take that modern cars.

How did you get the bell housing off, or did I just miss it??

Grtechguy

Yes, bellhousing off and on the new block. I ended up taking the crank and clutch assembly out through the bottom of the engine. #2 piston still in the old block.

Once the crank & clutch assembly was out, I was easily able to unbolt the bellhouse. It is entertaining how much of this truck needs open ended wrenches for assembly. Sockets just don't fit.

Always a good day when you go back to a project and the nuts&bolts are exactly where you left them. Today's 15 minutes of garage time consisted of reattaching the split drive shaft and carrier bearing.

All the nuts & bolts where just where I left them in the frame rail :)
