As I've learned today, 2 problems seem to exist with the Duratec/Arch frame combo. First, the height of the engine may necessitate a dry sump oiling system. Second, the factory throttle body/ECU setup has clearance problems near the foot boxes. Apparently, the people using Duratecs are getting the motors from Raceline and using non OEM ECUs. This requires a lot of dyno/computer ECU mapping time (way over my head). Any feedback on this info?
