I love my M103. Compression is either 10:1 or 10.5:1. Not sure, but who cares... High revver, smooth, rock solid bottom end. Plenty of meat in the block. Head is a little weak (kinda soft aluminum alloy). Know for eating valve guides and seals. Performs like a much bigger engine. Not much bottom end, but I never expected a dragster when I got the 300E.
