I wanted to say hello and get subscribed to your thread. I've owned several IDI Fords over the years, including one I'm currently working on that is in a '57 IH pickup truck.

My '86 was a crew cab dually and I set it up primarily to haul a heavy trailer. It excelled at that with an ATS turbo kit. With a larger turbo, methanol injection and a ZF5 I was able to easily get 18mpg unloaded. At the time I had no concept of eco-modding so no coasting or other strategies were in play.

My '57 has a 6.9l motor with the ATS van factory kit. Ford dealers installed these in many new vans before made them an option in '94. This one will get ARP head studs and I hope to swap in a ZF-5 to replace the C-6. Being a fairly light and somewhat aero old truck, I'm shooting for 25-26 mpg. Perhaps more if I glean some more gems from this thread!!
