That's a question to be answered after you get it running, part of the final tuning. The most I would do before first fire would be to check the floats. The jetting should be close to start with, floats can change because of handling and shipping. You can always call Eldo give them the 350 - 330 hp information and see what they say. After all the motor sounds like an out of the box specific build so specs will be solid, love dual quads myself.
