The ford efi is kinda restrictive, unless you can get your hands on the mass air but even then...
Heres something to read, its three pages but it does provide details, pictures and dyno numbers. The most impressive aspect IMO is the mention of an off the shelf mellings torque cam, which was used to generate 300hp and 400tq.
