How Big can a 5.2 get?

I was looking for a 5.9 but those are rare here in finland, pickn pulls were asking 1500€, its almost 1800$ :D
I was thinking about stroking, but that includes 0.030 overbore also and a 2000$ plus freight plus taxes so ill be in 3000$ then...

Oh, FINLAND I didn't notice your location. I'm in "the sticks" of the N end of Idaho state, and can sometimes "*****" about the lack of used speed parts, etc. But you guys must have it ROUGH!!!
