Why is there such a negative viewpoint on the 310 Waukasha. Is it just because of the 1855 early years or did the 1755 and 1955 have something to do with it. Several sites talk about re-powering with the 5.9 Cummins which I am aware is a very good engine but it is not the original. It seems to figure the 5.9 would make more power with 50 more cubic inches. I have also been told it is just the mere cost of parts for the 310. What is a collectors viewpoint?
