Thanks guys! It's actually an FRPP Boss block. The reason it's a 331 is due to the shorter cylinders on the boss. Although you can run a 347 with a 3.4" stroke, it is a better option to go with the shorter stroke of a 331. Although the bigger displacement the better for the most part, it's not a huge difference so I'd just make up for those few cubic inches with boost!
