I used a website that calculates, in theory it should go 8.6s in the 1/4, but I'm guessing more like 9s.
Yeah odd, the 662HP engine in the '13+ is a 5.8L, so I'm a bit surprised they didn't just use that as a base. But essentially if you're going to rework it as heavy as they did, it really doesn't matter which you've started with I guess.
I'd love to try to launch one of these with DRs on it.
