Looks like I was incorrect, you cannot put the larger 7.3 studs in a 6.9, see link below:

I believe R&D put the larger studs in a 6.9, it's definitely an involved process requiring machining not just drilling and tapping. Perhaps somebody else with the history will chime in.
This is solid advice. If you are really planning on compound turbos and high boost, and you are going to go through your 6.9, you should have the machine work done to the block to accept the larger studs that the 7.3 came with.
But the 5 gallon bucket has the added advantage of "strengthening your core", especially if you get it "tipsy" reaching out far. You know, a yoga instructor or personal trainer will charge you money for that kinda workout.......
+1 on what chillman recommended: go get new caliper pins, they are available and cheap. The squeaking you are hearing and the excess rub on your rotors is most likely due to the caliper pins allowing your calipers to move around too much. The rubber that inside of them gets dry rotted and if...
That truck in the video is in beautiful shape, but 40K for a normally aspirated crew cab dually? If there’s any hill in sight, that truck will struggle to pull anything but a landscaping trailer. By the time you upgrade the fuel system to pull anything you’ll have $45K into it. NFW......
Not to hijack this thread, but where are the best OBS lenses to be found these days? I don’t care about what technology bulbs, but my lenses are pretty cloudy.
I really like a front mounted hitch, but I don't like to lose ground clearance if I can help it. I built this front hitch on my old F250 and hid it behind a flip up license plate bracket. It was also kind of handy if you wanted to put a hitch mounted platform on it to stand on to work in the...
After a little more digging, I found a couple more part numbers, edited the original post to make it easier for those who might be looking, but here's where it came from:
I was told that the Accuride 28511 is obsolete and is superseded by 29577, and the Accuride 28512 is obsolete and superseded...
Very nice set up to support higher boost levels safely. The high boost Grand National crowd refers to water methanol injection as "free octane": maybe you should call your set up "free cetane" :cool:
Just wondering: who bent your intercooler piping and what diameter is it? They look very...
Good morning. I had the center section of a single mass flywheel clutch "break away" from the section around it that had the friction material on it. I can't really explain how this happened, but it did make some noise and act funny about a block away from where it finally broke away...
I’m hoping the accuride part numbers help others identify what they have. With less than 1/2” of offset between the two, they are not really easily identified. I was initially under the impression that the deeper offsets were only offered in the round hole steel wheels, but the two I have are...
Doing a search on this will yield contradictory results on rub between rear tires as well as the rub on the front sway bar. After buying some wheels and doing a little measurement, I believe I can shed a little light on this subject.
So it appears that there are two different dually wheels for...
In an OBS, Group 65s. I bought blems from Interstate.
In a bricknose, if you can make the room to run Group 31s, I would do it, and I believe there should be some history on bricknose installation requirements if you do a search. Group 31s are always available (think of all the heavy trucks...
You have identified one of your problems. Fix your glow plugs, it's not that hard.
Good job letting your starter rest/cool between initial starting attempts, but you should really think about a new starter as well. IDI's need enough speed to start. Remember, it's compression to ignition, and...
Just wondering: what's your idle speed according to your tachometer? Might be something really silly like the throttle stop screw backed off just a bit. It's common to turn up the idle on manual trucks with single mass flywheel conversions to quiet down to gear rollover noise. If it were me...
I love to gamble: something in the valvetrain broke, valves are crashed into the piston BTDC. It doesn't explain why it won't go backwards, but that's my wager.
The modular engines seem to have lots of valvetrain/phazer issues. Kind of a tough deal to do any in frame analysis, most folks...
Get a brass ball valve. Stainless steel is really tough to get to seal with NPT threads, if you don't use the right lubricant/sealer you will almost always smear the threads and get a leak.
So I'm a three strikes rule kind of guy. Counting me, you now have three people suggesting you privately ask this person to make this right, or publicly flush out this potential Hall of Shame candidate. It's pretty simple: whether I knew it or not, if I sold you something as forked up as that...
In my opinion, the added viscosity and lubricity are what makes this trick work. The injectors are hydraulically "fired" and they should go off a little higher with ATF versus ULSD as the slightly higher viscosity helps at the pump and the injectors. Your injector pump loves a dose of ATF as...
The fact that that's a F350 ambulance and not a van chassis is pretty significant IMNSHO. If that was closer and an OBS instead of bricknose, that might have to be my "poor man's Quigley Sportsmobile".
Somebody on here should snap that up as it's too cool to go anyplace else.
Thanks for the creative thought of machining the hub to match the wheels. I can honestly say I never thought of that. It reminds me of the first time I saw somebody turn a diameter down pm a vertical milling machine with the part in the drill chuck and a cutting tool in the Kurt vise. All...
