Power limits for LA small blocks?

I don't know what an R block or X block is, not that knowledgeable. But I saw no mention of the block being used in the Hellcat, or comparison of that engine to the LS engine.

Screw the Hellcat engine block and LS block designs. There not part of what needs to be done for a reliable high HP LA block in which this is about.
There more modern engines with updated design features which would be nice to have in our everyday blocks much like the imports I made mention of earlier also use.

But our blocks were never designed for racing, just people moving.

The X block was the first performance block released for the racer. It has a few nicer things about it that make it more durable and ridgid than stock blocks. The next in the series of racer blocks are the R blocks.

The are upgraded stock blocks that can hold some good power. The modern current system ocknengine block exceed the abilities of older race blocks.
(Or DANM well should!)

Im not super informed about all this, but you gotta consider what exactly "last" is. I mean, fuelers only care about "lasting a quarter mile plus burnout and staging". Maybe four rounds.

Aluminum blocks can "last" a little longer because there is the chance of welding a window back up. IDK what all you could weld to save a block but it has to add to the "last factor".

I would like to know the answer to all this too.

How long any engine will last before is a multitude of factors. Bust out your crystal ball for starters!
LMAO!

You could build a 500 hp engine that will last a half million miles if you drive like a scared old lady!!!
Or a 270 hp engine that will last months if you drive it like an insane teenager bent on revenge on a drug fuel rage!
