All good to know, it's nice that 5.0s make good power without any power adders. It just compounds how easily you can make tremendous amount of power from them. I think if I ever buy a new mustang it would be an auto. It's nice not having any boost drop off between shifts. I was really impressed with the 2017 ecoboost and 5.0 I drove this year. Just really good cruisers. Does these roush prep cars to do good on the dyno but not the real world? Just doesn't seem right they can fool people like that. A tuned stock Gt can probably run low 12s on slicks I assume.
