Good news. My recent purchase O290 turns out to be near new inside. A friend has bored 2 of 4 case holes to take O320 cylinders and I have 4 narrow deck cylinders lined-up. I do need a new sump to accept my Bendix servo.
There is a complete assembly available off a IO320B1A w/rear mount I will probably buy because that is what I had and all my controls will fit.
But the question. There are different sump configurations, different both internally and different intake tubes.
Are some better regarding flow and/or charge distribution? Or maybe the different internal configuration coupled with intake tubes make them close to each other? Of coarse FI may be better than a carb. too?
Just wonder?
