Favorite Crate Engines?

I wouldn't necessarily need something complete top to bottom, I don't mind pulling some stuff off my current engine like a carb, fuel pump, accessories, etc. How about stroker kits or something of the like? Is there anything out there for a reasonable price? I have no problem doing the engine assembly myself, I enjoy it, but it seems like buying parts isn't as cost effective as crate lately unless you really look for deals. That and I'll admit I really don't know much about combinations. I could find parts for good prices, but I wouldn't really know what would work together and finding parts for Mopars seems to be quite a challenge when I start looking around.
