I have some sort of O-320 and I'm not sure which one. It's a wide deck dynafocal. The sump that came on the engine is a different style from the ones we use on RVs. The intake tubes come out of the sump at a different angle which interferes with the standard Vans engine mounts. This engine came off a Long-EZ project which requires the funny style sump. If this is the original sump and data plate for the engine, then it's an O-320-E2G. But I don't have any good way of knowing that for sure. The project it came from was a hack job with lots weird stuff and no logs, so it's entirely possible that this is not the correct data plate for the engine.
So, 2 questions:
1. How might I confirm without cracking open the engine that this thing is actually an E2G? Is there maybe a spot on the crankcase with a part number in the casting which can be referenced to a parts list?
2. I want to run a C/S prop. If this is an E2G, from my googling and forum searching it looks like it does have a hollow crank, but it has O-235 style main bearings which don't work with C/S. Apparently converting between bearing types is possible, but does anyone know exactly what it takes? Is it as simple as just putting in different bearings when the case is split, or is there some sort of machining that would be required from a place like Divco?
Thanks!
