Well i may as well throw in my 2 cents worth here . Is there a piece of flex pipe somewhere after the down pipe from the turbo?? Or is it solid from the turbo on back ??? How are the engine mounts ??? Where is the probe for the pyro , in the manifold before the turbo or after the turbo in the down pipe . If it is before the turbo then then 1200 on a hard pull is hitting the max , after the turbo she is getting really hot . just where are the studs breaking at out on the end like on 1-2 or 5-6 or on 3-4 If they are breaking on 3-4 holes it may be due to heat and the weight of the turbo and the pipe and a flex pipe that is semi frozen or the fact that there is no flex pipe and you have engine mounts that are working to much . Just some ideas to think about as i am no expert on the 3406 B's . I did 90% of my trucking either with OLD Detroits Cummins and a couple Mack's and one 3406E . Each and everyone of them were wound out to the max . The only engine that i ever had a problem with manifold bolts or studs was on a 460 gas Ford and that was due to it getting way to hot . I have never in my life ever met a truck driver , farmer , or race car driver or equipment operator that told me he had to much power and each and everyone would love to get just a little more .

Today's Featured Article - The Day Mom Drove the 8N - by Brian Browning. My Dad was wanting to put in a garden but couldn't operate the 8N and handle the old horse drawn plow he had found and rigged up to use with the tractor. Well, he decided to go get Mom out of the house and have her drive the tractor while he walked behind the plow. You got to understand that while my Mom is a hard worker who will always help whenever she can... she had never operated farm machinery before that day. Dad got her out there, explained how the clutch was the same as in our o
