It's time for the Ford techs to chime in. 6.2 vs 3.5eb, which engine visits the shop more often? I love technology, but anything new requires time to debug. The ecoboost is not revolutionary, but is a big step forward for Ford. If they've done their homework, the 3.5 eb might be the next best thing, Ford is certainly pinning it's future on the Ecoboost engines across their entire line of vehicles.
