I have not ridden the park, but have many friends who do. When I'm on a 9m Nirvana, they are on a 9m Park. I have also ridden the 2013 Envys. The 8m Envy has more power than the 9m Nirvana. And the 10.5 Envy has much more power than the 11 Nirvana.
So, I would guess that the 10.5 Envy is probably equivalent in power to something like an 11 or 11.5 Park.
The 9 Envy is going to be really similar in power to the 10 Park.
hope that helps!
