Not sure if serious? The GT350 could be considerably faster than both around a race track without a DSG or AWD. Especially if this next car makes a decent amount more n/a than the Boss, is a little lighter with better suspension, brakes and much better weight distribution.
I should clarify, I was referring to muscle car fast stop light, drag strip 0-60 etc to win the muscle car war. There's a law of diminishing returns when it comes to straight line speed when it comes to adding more HP on a rear wheel drive front engine car with street tires. So it would make sense for Ford to go another route by making the car more balanced as Chevy did with the Z28 to get better performance and appeal to a much broader audience instead of one upping the HellCat by more hp.
