Never even heard of frame mounts cracking in a dodge 1 ton. christ the entire frame is boxed front to back.OR maybe they didn't want to have to build up the chassis to fit a cumminings in it.
I knew guys in New Mexico that would go get a new cummings 1 ton every other year (Ranchers, tax write off) and then take it striaight to the shop to have it braced up so the frame didn't crack behind the mounts or at the steering mounts.
I doubt the big ones are going anywhere, for smaller duty, there simply isn't a need.
As it is those 6L they are putting in the Dodges are about the smallest I could find on their website.
your buddies were doing things with their trucks that oil patch boys don't manage with deck trucks if they were cracking mounts/frames. Please don't confuse abuse with poor build quality.
also, you forgot the ".7" after the "6". please don't confuse a cummins with the disaster that was the 6.0L/6.4L International that got wedged into Ford's for a few years. bad, bad mills those were.
the 6.5L in chev halftons in the 90's weighed in at around 685 pounds, I thought. chev ran a "heavy half" style front end and they sold many a truck. I see no reason why dodge shouldn't, from a weight perspective, be able to do the same. well, other than the fact that a modern halfton truck is built like a car with a big trunk... *grumble*.
anyway, didn't know VM was supplying Chryco at all, ever. I'll have to educate myself a bit in that regard.
that is still to be proven. I haven't read any major publications, but have heard a couple of grumblings from guys in North Battleford, SK (little shit town to you guys, it's like the start of the oil patch in Saskatchewan) about the "Scorpion" 6.7L taking out con rods.6L? when has Dodge ever had one in a truck. Ford has and they sucked. Ford got their act together with the new diesel.
but it's quite possible it's a relatively isolated thing.
I actually doubt chev would use the same mill entirely. They might get VM to supply them with another, but even that, for advertizing reasons, would be a headache.
also, after the 5.9L CR was phased out, and the 6.7L was brought in, I didn't really want one. I'd take a 5.9 over a 6.7 any day of the week.
