Favorite Crate Engines?

So my dreams of a new hemi in my 67 project Dart are evaporating as quick as the money in my pocket it's taking to just get the car back to road-worthy. That being said, I'm now debating a small block crate or buildup swap since the car already has a 318 in it. So my question to everyone is, what in your opinion is one of the best crate small block options out there? I realize it all depends on application, but how about stuff like what's the cheapest (quality or reputable) build, most powerful, most reliable, etc. engine out there? I was just looking at a Blueprint brand 408 stroker mentioned in another thread, but it seems like a bit of a sketchy company. Ideally I myself am looking for something around 400+ horse that I would probably drop a blower on at some point down the road when I make some more money, but is there any good base out there I could start with or am I going to just have to build from the ground up? Does anyone besides Blueprint offer anything remotely near 400 horse for around $4000?
