Did you even read the article on th EB torture test? No 70's V8 (with 165 factory HP ) would come close to surviving that.The fact that “Even forum members on here have commented on their trouble free 100k+ mileage.” Even gets posted is evidence that people simply don’t trust the ecoboosts. 100k+ was a common place theme in the 1970s to show reliability - if 100k+ is the best ecoboosts can do in the 2020s then they have no chance.
There is simply no reason not to offer a V8 other than Ford is so committed to their ecoboosts that they cannot afford the embarrassment of building a decent small block V8 for the less than 3/4ton market.
Spare me the cries that the V6 is “good enough” I want the best not “good enough”. And the thousands of miles I’ve driven an F150 with the 2.7L I know that’s a frustrating engine that cannot get out of its own way. Now granted if your coming from a focus or some other small car it may be “adequate“ but for the rest of us we need a V8.
Also, assuming supercrew F-150 that's about half a ton heavier than expected Bronco curb weight.
Sounds like you need a first gen build candidate to get what you want. If you can't buy it, build it.
