Ive got a 425 3406b cat and a 310 3406b. The 310 is working twords 700,000 miles and I do believe it has never been majored. Its funny, the 425 is in a wheeler dump truck and the 310 is in a triaxle dump. I like how they pull. The 310 will pull hard all the way down to 1300 rpm's. The 425 won't lug as good but has lots more top end power and speed. I am happy with them. They are both 1990's and with this ecomomy they will have to last another 20.
