Stroke plus blower on a 95 M3

[SandSpeed]

Anyone know where I can find info on stroking a 3.0 S50 engine? I'm looking to make some decent power NA, and then possibly go with a supercharger, but I don't want to be like everyone else and just throw a Vortech on it and call it a day. I am tearing the motor down now, and will have the head ported, polished, and decked, and a valve job done, along with the block being acid dipped and both being inspected. Where should I go from there? Keep in mind that I am not rich, and will do as much of the work as I can myself. I rebuild internal combustion engines on aircraft in the Air Force, so I think I can handle the assembly stuff, and some minor engine work. Thanks,
