IT is in a E350 1 ton van and for some stupid reason ford gave it a V10, 4R100, towing package and 10,000 pound gvwr, 20,000 combined
WITH A D60!
Could you drop the Sterling 10.5 in there. That thing has been great in my F350. I have toted some monster loads over a lot of miles and it has not missed a beat in 185k miles.(knock on wood)

I do not think it would bolt up to my frame.
A D70 or D80 will, and the D80 is the factory DRW axle.
I am thinking of putting that in with my SRW leafs and hubs.

I can't believe I just read through 11 pages of crap, and the only info I gained is that no matter what you 10 holers say, my diesel will still put the hurt to it any time of day, empty or not.


And yes I'm still stirring the pot

Hey Brian- if you can find a chip that'll give you 400hp/700tq, then you should get into business with Bill rebuilding V10's for $1000..... and I can have my own concession selling bridges LOL. Hey Bill, I guess that you got a machine shop so you don't pay for machine work?

It certainly can't be any worse! If my back or butt doesn't touch it, it's vinyl. Although I can't complain, the leather on the bottom portion near my thigh just started to split. It lasted 6 years and 181K. My armrest split 2 months ago, so the leather outlasted it by a smidge. Once I stop my steering wander, poor braking and oil leaks, then I can start thinking about re-upholstering my seat. Since my passenger seat still looks and feels like new (where my wife sits), fixing my split seat will not be high on her priority list of financial concerns .

If I could make some extra money doing that as a side business, I would. Unfortunately, DP-Tuner, Power Hungry Performance and Tony Wildman have already established themselves atop the 7.3L tuning business.

no, but i have what I need for a normal overhaul.
I have done 5 different motors and never had to have any machine work done, just honing.
If the V10 had extreme wear it would cost more.
I am talking about a running motor with low compression, smoke out the tail pipe etc.
I can take it, put in new valves, rings, timing chain , rod, cam and crank bearings , valve springs, and all gaskets. fill it with fluids and it costs about $1000 for me to do it.
now if the V10 had not been cared for or driven tell it would not go any more than the crank, cams , pistons and machining the block would run $2000- 2500 for an overhaul.
The $1000 price is for a good block, cams , pistons and crank with no machining needed.

Gotcha- I rebuilt a 350 Chebby with machine work to block and heads (valve job) new internals, for about $600 all together, so I can see what you mean. It would cost me a bit more to rebuild mine unfortunately LOL...

If I remember right you were hauling a heavy load. Too much tongue weight can tear up a rear axle assembly. Maybe this was related to the failure?

You've calculated instantaneous road speed at a particular condition. You need to use average road speed instead. 45 mph average road speed (maybe up to 50 mph in some cases) is a rule of thumb used by on-higway diesel engine manufacturers and world class alternator suppliers that make products for those applications. It is used by CAT, Cummins, Bosch, Remy, Prestolite, Denso, Mitsubishi.... the list goes on. Because of my work I just happen to be in a position to know. Of course, you didn't know that when you made your reply so I can understand how you would question my assumptions.

I would find it very interesting to know how manufacturers do engine durability testing. Will you please explain?

the hubs are fine so it was not that.
The truck was sitting nice and level.

I don't care how on-road engine manufacturers rate them-that's not what we're talking about here. Standby generators are rated for continuous duty at a constant RPM. That's what the 3000hr rating at 3600 rpms is in reference to. It's also where the 60mph reference comes from. It's the same as driving the truck at 60+mph with OD off for 180K miles.
Ford's durability testing for the Modulars involved dyno testing the engine to determine the rpm at which peak HP and peak torque occurred. Then the engine is fully loaded on a waterbrake dyno and ran at the peak HP RPM and the peak torque RPM for 500 hours(if memory serves me right,it was 500 hours-I can't remember for sure the exact number). That's 100% load at 3250 rpms and 4750 rpms each for 500 hours. The engines cannot show any signs of failure in any form,or they are failed and the design goes back to the drawing board. If the engine is operated within the RPM limitations of the PCM, it WILL NOT HARM the engine.

I saw some video of Ford doing durability testing on the engine stand a while ago. The manifolds and exhaust were very bright orange. Pretty cool. Don't remember where I saw it. I think is was a 550hp GT 5.4l.

If the v-10 is so great and can out pull a PSD, why dont we see them taking the place of the PSD's in tractor pulls, etc? My buddy has a v-10 he has owned for 5 years already, pulling a 6k trailer most week days. He told me the other day that he drove a buddys 7.3 with a 40hp chip and he knew right then why people prefer the PSD over v-10. Also, I have a 2004 6.0 with egr delete, ITP R.R. fuel system, head studs, torque converter and SCT X3 set to tow and I get 17-20mpg on the highway with a 10" lift and 38" mickey thompsons, around 15mpg in town. NEVER will you see a v-10 get that mileage unless its going downhill with a strong backwind, idling.

At least a couple of the classes in tractor pulling "mandate" diesel fuel engines. I guess people could talk about how crappy the PSD is because Boeing doesn't use them in airplanes? A good engine for a truck should be based on what people use in tractor pulling event? Makes sense, for you I guess.
