Stop thinking brand. Extra power = Extra Heat = Thinner oil. Every one of those manufacturers makes oil which would be unsuitable, and oil that would be well suited. You need to match viscosity to expected oil temperature. Best example of this is the 2013+ Mustang 5.0. "Track Pack" cars get 5w50, regular cars get 5w20. Per Ford, there are no internal differences between the engines, just different expected use (i.e. oil temps).
Do you have an oil cooler? If not, get one.
As a good place to start, Redline 0w
30 or Amsoil ASL 5w30, or Motul 8100 X-Clean 5w30. You might even go one step thicker to Redline 5w30 or Amsoil 5w30 Euro or 5w40. There's little reason to use 300V unless you get a smoking deal on it, it's very similar to Redline but even more expensive.
I don't know exactly the availability or price in Canada, but Pennzoil Ultra 10w30 would also be a great choice and likely less expensive than the boutique oils. M1 0w40 or High Mileage 5w30 as well.
