Hi,
There really isn't an easy way to get more power from the US version 380. The compression ratio is the culprit...I think those were around 8:1. To get more efficiency you'd need at least 9:1 compression.
Regards,
Randy D.

Check www.deja.com - on the alt.auto.mercedes newsgroup a 380SL owner named Lee Sharp mentioned modifying this engine. I believe he mentioned polishing intake ports, but I'm not sure. He does a lot of his own work, so I'm not sure whether it would be cost effective to pay to have it done.
