This is probably super basic for most here, to the point of "put diesel fuel in your diesel fuel tank, but I'm posting this as a "just in case." McMaster Carr is a resource you HAVE to have on your bookmarks/favorites of your browser (or the app on your phone) From every piece to make Rob’s DIY AFC Live, to 3/8" 6061 aluminum plate for your trans skid plate, to that m1.59 torx button-head screw, they have damned near everything you need in a fab or mechanic's shop. https://www.mcmaster.com/

Ppump functions, upgrades, calibration and more. Yeehaw
I’ve had a bunch of questions regarding ppump upgrades, calibration, and stuff. The governor and the foot and that side of the pump seems pretty straight forward. Timing, while a bit of a pain, seems straight forward as well. Where I’m a bit uncertain is in the rebuilding/upgrading and the need for calibration. Here are a couple videos that seem to explain stuff, although I’m curious how accurate they are. Meyer (SP?) over on PDD did a good intro to the darned things here: https://www.youtube.com/watch?v=Og2I4mGu0u4 EdzGarage has a video (telling us NOT to mess with it) but some decent info. And while they don’t mention it, the “flag” for the #1 piston TDC is clearly visible. (the metal piece you align with the plastic insert dealio) https://www.youtube.com/watch?v=PBbdGI5mWFc Rob has a good video about upgrading the governor and the AFC assembly: https://www.youtube.com/watch?v=0XABcEDmgbA&t=712s There’s a solid video describing the actual calibration in an old Bosch video: https://www.youtube.com/watch?v=-aONWNgE1EI Aaaanyhow, here’s my question(s): if I were to take a 180 ppump, swap out the barrel, change the plunger to a 215 style plunger, and upgrade the delivery valves. Does this require a calibration? Looking at Rob’s video that discusses the spacers/washers on top of the DV, that they have to be saved or it will need re-calibration. (is that the same function as the shims on top of the barrel as shown in the Bosch vid?) I would guess that swapping a 215 cam into the pump would require calibration, regardless of anything else? The dang pumps seem fairly simple, but some of the details ilof it are like black magic or witchcraft.

Im spending the money elsewhere, so I may as well do the full thing, and get a rebuild/upgrade to 215. Thanks again, as always.

If I upgrade the plunger and barrel, does the pump need a full calibration?
Anyone ever used one of deez?

@Marc Brulotte they did towing and dyno testing in this vid, I think: https://youtu.be/EMK2v2InuXI?si=2rGrHcd5yRsNYUhe

But hey, getting a good hammertone finish is tough!
Camshafts!!
What’s everyone’s thoughts on camshafts in daily driver trucks? Are they worth the extra money? I’ve looked at a few but haven’t noticed if they have a lob for mechanical pump? I know people talk about using the Vp camshafts but they don’t have the pump lobe.

If you dont go big on a turbo, injectors and pump, the biggest benefit would probably be in reduced EGTs, and for towing, thats a good thing. But I have no clue what an appropriate cam for that would be (other than a mild lift, and not a ton of overlap). I just know that improved efficiency in air flow should benefit
