D1/D9 Blocks

How much HP can the D1/D9 Blocks handle before you start to run into issues??. Crank walking Etc...

That question can have many answers, but what I have seen is some where close to 800 hp you may or may not see cap walk. But cap walk is not the end of the world.

Many engines have had a long life and had cap walk all it's life. Tune ups have a lot to do with it.

Some people can run way more hp than 800 and not have it , and some can see it below 700.

But the block can handle a bunch of hp before breakage occurs. Most people move to an after market block at around 850 to 900 hp.
