A V-type engine has a common rod journal for two connecting rods. There are more differences than just the V-angle. All horizontally opposed engines I've seen (VW, BMW motorcycle, Lycoming aircraft, NSU motorcycle, etc) have separate journals for each rod. On V8's (chevy, ford, mopar, bmw), V12's (Jag, BMW) and V-Twins(Ducati, Harley, some Honda etc.) two connecting rods for opposing cylinder banks have common crankshaft journal. There was a flat V-type engine built for an Italian exotic car at one time but I van't remember the name. I think it might be the Cizeta Moroder but I'm not sure. Some other company made a W-12 with three cylinder banks but thats a whole other story.
