    2026 Best Oil Filter for the 7.3 IDI?

    I was wanting to know what oil filter do you use for the 7.3 IDI? For reference, the factory FL784 filter was rated for like 30 Microns nominal... Looking for something finer. Has anyone used the Baldwin B7513 that has a Micron Rating of 3 Nominal; 10 Absolute? Would a rating like this...

    Lip of sleeve at bottom of cylinder

    Thank you for your input. I have essentially arrived at the same conclusion after looking closer. I see in that diagram there's a step in too. only diff is mine is like .31" and that is calling for like a .20" shoulder. I've decided that given the rings and wrist pin are well above this area...

    CDD injection line issues

    I thought this was interesting... from the AERA bulletin for the 7.3/6.9 pertaining to injection lines. "Injection lines - Due to the .060" retraction of the injector nozzle on the 7.3, all 7.3 injector lines have been shortened by .060" However, all lines with the exception of #1 on F series...

    Lip of sleeve at bottom of cylinder

    Thank you for the feedback. This is terrible. I somehow missed it on pickup. This is the same machinist that messed up my first block and this is his replacement so I find it difficult he will be willing to make it right at this point. I will go see him today.. worst he can say is no. I had to...

    Lip of sleeve at bottom of cylinder

    Today I was assembling my motor when I noticed I have a somewhat sharp edge on 3 of my 8 sleeved cylinders. pressing a feeler next to this edge/lip I estimate it's about .010" maybe less. My machinist previously stated he added a 5/16 shoulder at the bottom of each cylinder for the sleeve to...

    Pre combustion chamber crack advice

    You can always run this by Justin's email at R&D. He builds these personally and has a wealth of knowledge. He may have precups too.

    Fuel tank showerheads

    I deleted the shower head and went with a fuel tank sump. $35 on eBay for billet aluminum. Drilled a 3-in hole in the bottom of my tank after thoroughly removing the fuel. Used 6an connectors to tie into the factory fuel line. Now I can use every drop of fuel and not worry about a shower head...

    WARNING about King Main Thrust Bearings

    I would be curious what your free spread and saddle width measure. I just used a quality set of calipers. For the rod bearings, as long as they are pushed into the rods and cap tightly and are not falling out on their own, you should be fine. Make sure you plasti gauge to check your clearance...

    I wanted to share an important "heads up" regarding King main thrust bearings that have been produced since 2024. Engine Tech branded 7.3 IDI main bearings are in fact King bearings just repackaged by Engine Tech FYI. I received a set of Engine Tech Mains from my machine shop a year ago and...

    CDD injection line issues

    I would imagine that if all the lines had increased length by the same percentage, timing should be just fine. You just might have to adjust base timing a little but after that, be just fine. But if not all are increased by the same percentage, I could see problems.. Maybe CDD has corrected this...

    Hi, has anyone used the Samco Sport silicone radiator hoses for the 6.9 and 7.3? Seems Samco radiator hoses last almost forever. I am planning to run Evans coolant and like the idea of hoses that will last as long as the coolant will ha. See below link...

    F350 80-86 Fuel Selector Valve Connector replacement

    I ended up choosing to keep the old style connector as I found an OEM fuel selector valve (FSV) more affordably than the OEM later one with the different connector. My original was still working but since I am in here, don't want to do this again for a long time so keeping the original FSV as a...

    Valve Recession and Fel-Pro's head gasket..

    Attached are my recessions and protrusion measurements. The others that have EX valves out have lower protrusion that I don't expect to have issues from. Recession is fairly close together HOW DID I NOT KNOW THIS EXISTED. Wow. I literally trashed a block because it had .010 too much decked off...

    Valve Recession and Fel-Pro's head gasket..

    This thread is so helpful for how to approach the clay piston to valve clearance with clay, solid lifters, and adjustable push rods! I guess I will prepare to to take these measurements and hope for .030" clearance, .015" minimum. Oilburners.net https://share.google/DZ8bGvnvJEQCCWQ5k

    Valve Recession and Fel-Pro's head gasket..

    Hi, I was wanting to see if someone could help me with a technical question. I am in the process of assembling my 7.3 idi and am taking protrusion measurements and valve recession measurements. For background, deck was decked .011" and I am using Mahle's .010" reduced pistons. I am using R&D's...

    F350 80-86 Fuel Selector Valve Connector replacement

    From what I have read, it seems it is nearly impossible to find a replacement connector for the bullnose 6 port FSV but thought I would ask in case a solution exists.. Does anyone know where I can find this connector? Is there anywhere else in Ford's vehicles from that time that used this...

    6.9 vs 7.3 idi oil fill/injection pump cover change

    Hi, I was wondering if anyone knows why IH changed the oil fill/injection pump cover design on the idi? I have one of each of these covers and trying to decide which style I want to use. I see the 7.3 has cast lugs on the back side but am unsure their purpose. was the 6.9 problematic? A small...

    7.3 IDI Block Deck Flatness / Trueness Spec

    Inspected Block today. Getting about .002" between the middle 2 cyls on the P/S bank. Also appears one sleeve slightly protrudes above the deck ~.001". Asked to have them deck .003" on both sides and see if it'll clean up. After that should be set! It's might be in spec but I have room to deck...

    7.3 IDI Block Deck Flatness / Trueness Spec

    Thank you two for the kind words and feedback. This is a build that has suffered from scope creep and is one of those things that I want to get right the first time and not have to come back and do later. When this engine goes in I'm hoping to never have to take it out again! I'll work on...
