    Block repair... Advice needed...

    Thanks. I was looking at the high performance Melling series before. I might revisit the idea of reducing the bore to 6.9 pistons. First things first though, let's see what I can come up with for a block...

    Block repair... Advice needed...

    I certainly see your point but it still did not answer my question(s). I bought a Jetta TDI two years ago and I've managed to add 90K to the odometer in that time (!) Not that I ever intend to commute in my truck that way, but mileage has a way of sneaking up on you in the wide open west. I'm...

    Block repair... Advice needed...

    By this you mean a rebuild with all 8 cylinders sleeved correct? Once sleeved, can a block be built again in the future? As in old sleeves removed and new sleeves put in? Or is that the final use that you can get out of it?

    Block repair... Advice needed...

    R&D is supposed to carry them at some point if they prove their worth. Right now it looks good, but I don't know what Justin's plans are as far as ordering more. He got the first set in a customer's truck, and two more sets are being made now for myself and another FTE member. If you want to be...

    Block repair... Advice needed...

    Have they been bored oversize already? I know this is a controversial subject but if they sonic test okay, going .020" overbore is only about 5% of the original wall thickness. Seems like that is a preferable result over the major surgery of a full re-sleeve. Am I missing something major? There...

    Block repair... Advice needed...

    Yes, sorry... I should have explained that the photo was just something I had on hand to illustrate the level of rotating assembly carnage. My machinist showed me where the three center bearings spun, and the two ends had hour glass shaped marks where the bearings were wobbling as the...

    Block repair... Advice needed...

    Thanks towcat! If I strike out in Arizona I might actually take you up on that. I have family in the Bay Area so I could easily make a trip out of it... As far as the special bearings or building up material with welds, this is what my friend in Czech Republic suggested. But they are more...

    Block repair... Advice needed...

    Thanks for the confirmation guys. I hadn't thought about the gears up front either. That just won't work. I am putting a lot of $ and effort into this truck and I want it to be done right. Good core engines are hard to come by, but there are two possibilities at the junkyard right now that I...

    Block repair... Advice needed...

    I need some advice about block repair... I pulled a junkyard 7.3 and took it to my machinist. He said the cylinders look good, but the three central main bearings spun in the block. He said it is possible to cut the block where the main caps mate and line bore the crank axis but he did not...

    What to do with a "spare" 6.9L block?

    Usually the rebuilder will add a tag with the main part of the serial number engraved on it:

    What to do with a "spare" 6.9L block?

    Casting number is on the driver side below the oil cooler, down by the motor mount. Casting number doesn't help much though.

    What to do with a "spare" 6.9L block?

    That's odd... that is right where it ~should be.... I'm guessing that surface may have been milled during a rebuild. Don't know why they'd do that though unless the head surfaces were decked enough to prevent the valley pan from sealing. Is the oil pan off? Can you look up into the bored and see...

    What to do with a "spare" 6.9L block?

    What is the serial number stamped next to the IP gear cover? If it is a late block with bolt in style piston oilers I might be interested. As far as a shop, Joel at Flagstaff Engine and Machine is the "man". Great guy and top notch machinist. I'm sure he would build an IDI if you don't want to...

    how to make real HP with your IDI

    This is the place that offered it: http://barnetthighperformance.com I don't see any such thing on their website now, you would have to give them a call. My thought is that it would be a very expensive way to add some power. I wish that IH/Ford had gone this direction when increasing the...

    how to make real HP with your IDI

    What?! I looked up numerous sources and found the auto ignition point of No.2 Diesel fuel to be around 210*C (410*F). On a cold start that is the temperature that must be achieved in the precombusion chamber for the engine to start. In my experience, the enthalpy of compression is not enough...

    how to make real HP with your IDI

    I was poking around online and there are actually dual disc clutches for the ZF-6 also.... still the major problem is that we can't use the PSD flywheel.

    how to make real HP with your IDI

    Do you know how cold that 'cold-star' was? Are we talking negative digits, frosty morning??? What kind of cold start? And are you saying he was using ether AND glow plugs? Thought that was a big no-no!

    how to make real HP with your IDI

    This is an interesting idea, but the real problem here is that you would have to be able to use the dual disc Dodge flywheel. Getting that to bolt up to our crank, match balance it, and then find a way to get the NV5600 to bolt up to the engine and a starter sounds like quite the headache if...

    how to make real HP with your IDI

    I think that is what Justin wants to make (eventually) is a custom gear housing to mount an 8 cyl Bosch V pump. That would be awesome, but costly. The NV5600 is not any more robust than a ZF5. A ZF6 is a tad bit stronger and not hard to adapt, but the real issue isn't the trans itself it's the...

    how to make real HP with your IDI

    I don't have a build thread yet but I will. There are just so many dead-end "idea" threads out there that I wanted to have all my parts and some good solid progress going before posting it up. For my uses and my budget the 150cc is a good place to stop. Remember Justin's bronco was only...

    how to make real HP with your IDI

    I discussed this quite a bit with Justin before ordering my pump. I told him I wanted a DB4 and he asked me 150cc or 180cc? I told him I wanted the all-out 180cc because my long block will be capable of supporting it so why not? Right? Well, a couple sacrifices had to be made to get that much...

    how to make real HP with your IDI

    Justin shaved down forged PSD rods because they have bigger fasteners than IDIT rods. He also wanted to see if it will work since there are even stronger aftermarket rods made for the PSD that he could use for his P pump build if modifying the stock forged rods works.

    how to make real HP with your IDI

    That particular engine actually was a stock NA bottom end except for file fit 2nd rings and his experimental 5.0 cam. He used Type4's stainless valves, comp 910 springs and ARP studs. That's it. When he dyno'd 401 hp at the wheels (fuel only) it was a spur of the moment thing. He wasn't happy...

    Valve lifter recommendations

    Thanks. I will definitely give that a try and see if they smooth out. They were not the most expensive lifters but they were not cheap either.
