so back in December i decided i was going to rebuild the 7.3 out of my parts truck, now months later after much struggling and lots of scouring around here for information i finally got it finished.
old engine was pretty dirty and i had no idea if it ran, was told it "dropped" a cylinder but didnt know what the guys definition of dropped a cylinder is, one of the injection lines on it had clearly been brazed (quite poorly) so i thought maybe he just plugged the line off accidentally when he brazed it. on teardown i found that one of the injectors was pretty well locked in the injector bore and only the upper half came out when i pulled it (i forgot about the other half when i took the heads to the engine shop and apparently he missed it and it was stuck good enough it didnt come out in the tank). after getting all of it cleaned up it seemed to be in pretty good working order so it was a fairly straight forward rebuild. went with R&D Stage 1 cam, R&D 90cc injection pump, R&D stage 1 injectors, used a victor reinz full gasket set for all the seals, south bend clutch and flywheel, comp cam 910 springs, ARP head studs, and had a buddy make me a freeze plug tool.
ill just post pics of what i started with and the end result
