Some insight on my build

What are you going to do with the car? I would also be concerned with a .070 over 360. A street car going to shows/cruises some full throttle fun, sure. If it’s a matter of what you have at this moment, that’s understandable. We have all been there, the more power and abuse you throw at it the more concern I would have. I’m no where near the cliffs edge for stock blocks, but .040 is the limit, over 4” stroke and it gets a very short fill. You get Better ring seal. increase stroke can be hard on cylinder walls. You can get a stock block to survive at insane power levels, turbo ect, but do it wrong and there is zero margin for error. Again street car sure, something more and it’s a ticking clock.
