And where is there any info on this? A quick google search just brings me to the 6.8l v10 that's not exactly new.Big things appear on the horizon for Ford V8 power. I am surprised no one has not heard of the new 6.8 liter Windsor engine. Ford is really giving us some new performance Mustangs. To have a 6.8 liter V8 ready for production in 2022 is amazing.
I believe it was in one of REVan Evan‘s YouTube videos where they weighed a 7.3 and a Coyote. The 7.3 was about 130 pounds heavier. If there is a 6.8 and it is a shortdeck version of the 7.3, it will still be probably 100 pounds heavier, unless they do an aluminum block.I doubt it would weigh much more than the coyote... maybe 30 - 40lbs... less than a blower. The coyote may be aluminum, but those heads are huge and heavy.
There are lots of reasons why a big block swap is not appealing, but buying a big block Mustang from the factory is another matter.
