How can i make 700 horse from a 410 stroker

I bought a Ritter cast block, ran new $2700 shipped and had about $3000 machine work for the basic the only thing I did that cost more was the addition of roller cam bearings. Then I drilled the holes in the deck for the heads I was using. The aluminum blocks go for a lot more. Plus the cast iron block might have gone up since I bought one back in 2017.
