You might want to reconsider, the 225 does not have a lot of ptential, even maxed out, you will spend 3x what a good small block will cost. If you are doing it to be different, then thats cool. But I know someone that went and built his /6 to the gills with fuel injection, it cost him $12K and he ran a 15.0 in the 1/4. He is now getting ready to swap in a big block. Even with all the things you will need besides the engine, you will still spend half of what the /6 will cost you.
Something to think about.
