I have some experience with the Ecoboost with my Flex I have been anxiously waiting for this truck, I have had 3xF150 EB trucks so far and looking forward to this one. The truck with the plastic manifold has fueling issues but guys are finding they are lifting heads and taking out bearings around 600WTQ on the existing engine. In talking with the engineers at SEMA we had discussions about the capabilities of the new motor and differences. They were aware of my car and said we should be able to easily make 800WHP on stock engine with mods, but of course not recommending that. My sales guy is just waiting to let me know when I can order, I can't wait to get my hands on one, hoping within 2 - 3 weeks depending on availability of tuning I'll be at 500+WHP quickly.
