    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...

    Valve lifter recommendations

    Hi, does anyone here know the original manufacturer of the valve lifters? Or alternately have a brand to recommend? I have heard a few horror stories of aftermarket lifters that resulted in bent push rods. My engine ran out of oil because of a broken oil gauge feed tube. The lifters collapsed...

    Anyone tried this 4,000 rpm tach in their slant nose IDI?

    There have been a few threads around lately with guys looking for a factory diesel tach for their 83-86 slant nose IDI's. A good friend of mine has been searching for one, and I came across an odd ball 0- 4,000 rpm tach in a 1980 F700 with either a 370 or 429 gas V8 engine. I did a little...

    Hi guys, I am in need of some advice on 6.9L block differences. I have checked the net and dug up quite a few threads on the subject, yet I still have more questions than answers. The one useful piece of literature I found concerning s/n breaks was this: Now for my questions: 1)...

    ZF input shaft play: new bearings or full rebuild?

    Question for those of you who have rebuilt their ZF's... if there is noticeable input shaft play, does it follow that the rest of the transmission needs rebuilt (bearings, synchro's etc.,) or if the rest of it seems tight should I just replace the front cone and roller bearing and the related...

    Opinions/experiences with the "typefour" ZF mod

    Hi, new to oil burners, some of you may recognize me from FTE. I understand that some of you here have done the "Typefour" ZF mod, i.e., re-drilled the bellhousing bolt holes to fit a 460 ZF to an IDI or vice versa. I am a little shy of this modification because of structural integrity, so I'm...
