If there was an EcoBoost 5.0l or 5.2l, wouldn't that conflict with the 3.5l EcoBoost that's in the 2017 GT? I would imagine Ford would just use a version of the 3.5l for the GT500. Just like Ford used a supercharged 5.4l V8 for the 2005 GT and then later used that same motor for the 2007 GT500.
Although white with blue stripes pay homage to the GT350 nameplate, it just doesn't look right with the styling. To me, it just looks a lot more better in that dark gray that was shown in the CGI model.
My 2012 Boss came in with .3 miles on the odo. I personally picked it up straight from the train yard and drove it to the gas station behind the dealer and to the dealer itself for inspection. I just couldn't risk someone else driving the car. I didn't even let anybody detail it.
Dude, put whatever badge you want on the car because it is after all, your car. But if I were you I'd find some reproduction SVO badges as a tribute to the SVO Mustang. The EcoBoost perfectly fits the nameplate and will not offend anyone in the Mustang community.
