My $.02. For normal driving you will want to stick with the stock US version 380 cams or cams that will give the equivalent duration and overlap when appropriately timed. I have owned both the EURO 380 with 9.3 to 1 compression and longer duration and greater overlap cams and US 380 with 8.2 to 1 (from memory) and shorter duration and overlap US cams. While the EURO engine will still breathe at 6000 rpm with 200+ hp it has very little low end torque and doesn't hit its stride until 3800 rpm or so. While it could do a respectable job cruising the Autobahnen it didn't do so well from stop light to stoplight. On the other hand, the US cammed 380 performs more like a US engine from that era. It has good low end torque, fuel economy and respectable performance from a stoplight until 4500-5K or so but made do with only 150 hp or so. If you go with either the EURO 380 cams or big block cams your 380 will probably be terribly overcammed and your wife will likely kill you due to the lack of low end grunt. Mark
