Does your 310 have cross feed capability? It would be be wise to plan for a possible engine failure a the furthest point from a safe harbor. I would expect you would be close to one mile per gallon, so with reserve of at least 10% or better + unuseable fuel, probably at least 5 gallons per tank, no. This answer probably comes too late for your trip. But that is my thinking. I have to a 2000 310 with 5.7 EFI's. 160NM is the furthest I would go.
