Default 306 or 331 ?

We're looking to drop a crate motor in our 88GT over the winter. Also looking long-term to add a supercharger. Thoughts on going to a 306 vs 331?

I've heard you can make the same power on the 306, but you'll need more boost. Also heard the 331 will provide more torque.

Any comments guidence appreciated
