So I am thinking with a 70% increase in power should be good. Torque is a beast from idle to 5500. Highest at 3600. According to the calculator, I will be over 2000 RPM. From the engine dyno that is around 650 TQ and 300 HP.

It's really not a function of how much torque is available at low rpm, it's more of a function of the camshaft specs and how much overlap it has. If there's a lot of overlap, it won't be happy being lugged, no matter if it's a 1000 cubic inch engine.
