O2A vs 337 Cruise Speed

[andy meyer]

Would it be fair to assume, that if pylons and antennas were removed that an O2 should then cruise at similar speeds as a 337? The O2 I am looking at has a lower empty weight then the 337G by almost 100lbs, and I believe it was weighed after complete major restoration. Is there other components of the O2A that would create substantial drag? Maybe no spinners... which a guy could always add if it makes that much difference. Others?
