Fair price for 360 magnum?

So i paid $300 for it TBI to pan Fan to torque coverter and the stand it was on. Valve covers had a slight film of oil in them no rust whatsoever in the water pump housing or thermostat. Did a compression test on the stand all cylinders were within 10 psi of each other lowest being 155 highest being 167. Ill tear into the motor more this evening but from the looks of it this thing never even leaked any oil and sat covered inside a shipping container for the last 6 months.
