Fair price for 360 magnum?

I bought a '98 Durango with a slipping trans and 189k on the clock for 400. I sold the trans to a local guy as a core for $150, sold the body to a junk yard for $50, and came out with a $200 engine with every accessory and piece of anything I wanted. I see them all day long.
Wish I could find a complete runner for $400 around here.
