This is not a new undertaking for Ford. Ford sells a ton crate motors. This is already available on the Ford Performance website. https://performanceparts.ford.com/part/M-9000-MACHE

There has never been an FP part that was given a part number, but never made available. They have offered pretty exotic engines, and even the components to convert lesser Mustangs into special edition ones.

It is highly unlikely Ford will renege on this.
