Just hypothetical musings about max power potential

Okay so I was thinking about this. The "word on the street" is that the max power capabilities of a standard sb block is about 700 ish. People claim the block will split. I'm guessing in the main webbing somewhere?

Anyway. What causes the cracking? It's not just power itself. It must be some combination of factors. RPM. Stroke. Cylinder pressure. Actual load (i.e. weight transfer and traction actually putting load on the engine).

RPM: It stands to reason higher RPM leads to higher cyclical loads on the block. So a lower rpm engine should withstand more power right?

Stroke: It stands to reason that a longer stroke would tend to stress the block more compared to a shorter stroke. Just pure physics. Pulsing loads at a longer stroke is going to create higher amplitude of stress.

Cylinder pressure: it stands to reason that higher cylinder pressure would create larger pulses of energy for the block to absorb. Similar to longer stroke?

Actual load: are you running in a high traction situation at a drag strip? Or just spinning the radials on the street? It stands to reason that the former would be harder on the block.

Other considerations? Anything I've not thought about?

So I was thinking that, perhaps the best strategy for maximum output, would be a short stroke, lower rpm, higher boost engine. Like a destroked 340 with a lot of boost, but tuned to kick in earlier in the rpms. Say max 6000 rpm. What would the power holding capability be?
