Absolutely, but let me expand the answer based on my situation.
1. I did not make a decision to go to the 320 just to convert to a 320. The O-290 provided very good performance and if there weren't other concerns I would have stayed with the O-290.
2, The O-290 was having oil leaks around the cylinders which turned out to be unrepairable
3. Based on the inspection I was concerned there might be other problems with the engine and the cost to tear down for a complete inspection and replace the cylinders as an O-290 was more that 1/2 the cost of a complete overhaul.
4. At that point the cost difference between doing a complete overhaul as an O-290 or boring out the block and making the engine an O-320 wasn't much so I made the decision to convert it to the 320.
