average $ difference between used 160hp 320 and 180hp 360

Hi guys,

I have been looking around at the prices for used 320's and 360's and they seem to be all over the map. Can someone give me any kind of guesstimate/rule of thumb regarding the premium I would pay if I chose to buy an O-360 as opposed to an O-320? I am looking at both RV-6 project I might start in the summer. Any help or guidance would be greatly appreciated.

I am flying behind an O-320 for the past 14 years that I got for a very good price. Wish I would have paid for the 360 up front even it it would have taken an extra year to finish the project.
