I was hoping to get some suggestion from other forum Stove Bolts.

I am restoring a 54 235 engine. The engine had 56 K on the clock prior to sitting in a barn since 1996 and freezing up. I attempted the pouring the good penetration fluids down to the pistons etc. I t never unfroze so I went ahead and started the tear down.

I now know why it never broke loose. The two pistons removed show one with the wrist pin area solid and frozen. Now I am in my dilemma as I need to have the crank shaft to move to get the other four pistons to remove. The engine is still frozen even at this stage of the game with four pistons still in the block.
I went ahead and remove the bottom rods and bagged and tagged each to show original location thinking this might give some edge to remove the rest. The pistons of course need the crank to move to get to the unit to allow the rest to clear. I have not pulled the engine from the unit as it has plenty of room and I would need the engine crank to move to get the bolts on the flywheel loosened. I did spray more penetration oil to let it soak more. I will upon getting the pistons out take the frozen ones to the machine shop and let them press them out and not damage.

My next possible steps:
A: To hopefully get an answer from a similar situation.
B: Consider lightly tapping the non-rod area of the crank to see if it will budge.
C: Remove one bolt from the crank to see how much thread I have to slightly lower the front first cylinder to get the inch needed to remove the piston and then work on the rest.
D: Pull the engine and Trans and hopefully get the leverage on the front vibration damper to put extreme pressure and attempt to break loose.

FYI: I was amazed on the block with the smoothness and non wear showing.
