Anyone done a strong 400 build ?

Id be extremely interested in an stroker combinations starting with the 400 block. 598/499/500/512 ???
I've built a bunch of 400 based engines over the years. The 512 is a good street combo, the 470 makes a nice race engine. 700 hp is fairly easy to make with Trick Flow 270 heads, 800 hp can be done, but is probably at the limit of a stock block. This pump gas 470 made 780 hp.
