There were pictures on this board, but the "turbo" section got killed recently.
Here are a bunch of pics over on theturboforums.com of the build and dyno results.

Are you trying to make 400~450 wheel HP, or Engine HP? The reason I ask is if you're only trying to make 400 Engine HP, I would probably steer you away from the turbo deal.
Honestly for all of the fab work it takes, and the parts that nickle and dime you to death, I don't think I'd bother building a turbo motor if you're only trying to make 400hp at the crank.
By the time you build the hot side, get the turbo, buy all of the flanges, buy the waste gate, blow off valve, carb hat, convert the carb, etc... It doesn't make a whole lot of sense to build the turbo motor. I think 500 is a more realistic break point for where the turbo really starts to shine. At that point you're starting to get pretty radical with cam/compression/heads/etc to make 500hp at the crank with a small block.
All just depends on what you're trying to do though. I'm more then happy to help with info for your build though.
