Default Stuck Front Bolt

I am trying to disassemble this RX8 engine that was rusted. The front bolt will not come off. I've tried all the tricks I know,
Impact no go. Heated Propane Torch, no go. Heated Cutting Torch No Go. Massive Breaker Bar, no go.

Suggestions? Just call this crank junk and cut off the bolt head to get the motor apart? The crank is one thing I wanted from it! (yeah I know, it is an eccentric shaft..)

Can't undo the front bolt!

I’ve used a product called “Yield”. It’s amazing for seized bolts. Try track some down. Repco sells it in Australia
