I hope I magnetize the fruitloops out of it. Replacing a stroker crank is harder than replacing a pump. I keep hearing the cranks are becoming hard to find and I don't want to find myself not being able to find one because a .5mm piece of metal went rogue and took a journey through the oiling passages.
That magnetized oil pump is gonna suck up all kinds of metal..and it could result in it locking up on you while that expensive crank is still spinning.....then you get the joy of replacing BOTH of them.
It's never a good idea to have anything that uses gears meshing together to work magnetized..................worst case, it sucks in a big piece & locks up....best case, it slowly starves the engine of oil from all the crud it picks up.

Either way, it means $$$$$

That was my thoughts too. Magnetizing the oil pump and gears might not be a good thing. You want that stuff to pump on through to the filter and not hang onto the gears and eat them up.
How is any metal going to get past a 7000 gauss magnet with 40lbs of pull force on the sump? The sump may become magnetized, but I doubt that's going to extend up into the impellers.
This is any metal that makes it down into the oil pan. There will already be magnets around the perimeter of the block to catch anything created on the spot. I've seen other guys on other hot rod forums doing this as well. After I ordered my cam. I wanted to do all of it but didn't want to pull the engine out again. My oil changed that.
I'm going with the magnets regardless. They're on there way.

I was going by what you said... You said "oil pump" not "sump". Being on the sump shouldn't hurt anything. Anywhere but the body of the oil pump it's self.
I found tinier particles in the oil pan, but no where else. The oil pump is pristine as a jelly bean, and so is the cam. I need to reinvestigate the head. If I can't find anything there then it must be the stuff from the lifter that sprung apart. I can see small scoring marks on the fact of the lifter that came apart but the rod looks clean. I'm guessing they use cheaper materials on the lifter faces.
CompCam lobes are skinnier than MOPAR, but it looks like the wear patterns fall within the lobes. The only part that doesn't sit well is that the MOPAR lobe tips have a wear pattern that goes all the way across.
I am contemplating, but I am pretty sure the Comp-Cam is going in. The whole setup with all the oil and having it nitrided set me back $450~.

1) Oil pumps don't use impellers...they use gears....the gear meshing action is what forces the oil thru the pump. They are also positive displacement, which means if the gears are turning, oil is pumping....it also means the only way to stop it is to literally break the input shaft, or turn the engine off.
2) I don't care what gauss rating the magnet is. OK, so it has a 40 lb pull rating...the pump is a positive displacement pump like I described above putting out 80 psi .....guess what...80 is higher than 40....it wins.
3) Again, you said pump not sump......which is why we said what we did.

He admitted this and understands. We are all back on track again.

I guess I'll save the MOPAR one for a rainy day.
Hey...The comp cam has too many lobes... lol
It's universal for earlier engines with a mechanical fuel pump I presume.
I know..he admitted #3, but based on his previous posts, he didn't know or realize #1 or #2
but yes, back on track....for now....lol
Now I have to admit that I am confused by what you are trying to explain with #2... Are you saying that the pull of a magnet will affect the oil flow? I must have missed something somewhere. Lol

No, I am saying it WILL NOT.

Meaning....the magnet has 40 lbs of pull....but the oil pump puts out 80+ psi...so even with 40 lbs in 1 direction, the 80 psi in the other direction wins.....
And a positive displacement pump like the oil pumps will pump until it breaks if the flow path is blocked.....which would be well above 80 psi.
That doesn't directly correlate. You're comparing 40lbs of magnetic force on a piece of metal in the body of a pump, vs 80psi of fluid pressure at the output of a pump?
Not that it makes any difference anyway. The topic of discussion was sumps, not pumps.
