Let's hope you don't find too much more junk, or if you do NONE in the vital parts!
Side note- Every time I see this thread title I think "Needle bearings circling the drain"...

Ok little progress, pulled the pushrods and used a boroscope and they were clean of debris. I'll try to find a small magnet, but I don't see anything besides a little grime. This is cylinder 4 rear most lifter, both the tray and lifter were debris free from what I could tell

Inspecting the valve top I could see slight scratching, and then inspecting the rocker I found the same slight scratching. It's probably a wise idea to replace the rocker

Fingers crossed it seems pretty minor

I don't see a point to pulling it. If I'm going to tear it down I'd probably sell the long block and start over.
I'll pull the pan and replace the pick up tube and o ring. If the pan has a bunch of metal shavings I'll start heavily weighing my options. I should be able to skim a magnet through the sludge and see how much is in there, what gives me hope is that the drain plug with all the needle bearings did not have any shavings anywhere on it

You have to be kidding, That shrapnel has lived in the pan for 10 years and if he hadn't changed to a magnetic plug 2 weeks ago he would still wouldn't know about them. I would upgrade the trunions since the rockers have been pulled but that's it. I wouldn't even drop the pan, If the parts were small enough to get sucked into the oil pump they would have done it long ago.

Post #20 is the way some people think, I know I couldn't sleep knowing
something could be wrong, besides it's a good excuse to pull the engine out.

Yep all opinions are welcome. I just don't see any value in pulling the motor. I wouldn't be re using anything from it, I don't have an engine build upgrade path. It would be me pulling the trigger on parts just to get a forged rebuild on a few weeks of research.
Heads, $1500?
Camshaft $300
I'm already two grand into a setup without any machine work or internals. I'd need to upgrade my fuel system, rewire in a new 99+ ecu, have the new setup tuned. I'd rather just plop in an ls3 crate and sell my old core needing a rebuild. It's just a fun weekend car, I'm not racing it or going to dyno days, it's my fun toy.
Just received the CHE trunion kit from TSP, shipped out with next day delivery.
These things are freaking beefy. The trunions are Heavy, I mean they come out looking like an engineered forged piece

I am surprised the original f-body oil drain plug wasn't magnetic. All the trucks,gto and my 2008 vette all had factory magnetic drian plugs. When we opened up my friends sbc 383 we found the oil pan windage tray broke off from its welds in the oil pan and a big piece of it broke off and layed in the pan for many years. Motor ran fine. Can't believe it never had any problems since it was run to redline many times. Motor is back together with new pan and tray and new heads to replace the cracked ones.

The CHE trunnion kit looks awesome. Are you soaking the lifters in cleaning solution? the 4 in that pic look nice and clean. Is there a way you could count all the rollers and maybe do a count of a known good one to see if the numbers match?

I wasn't missing any needles, all of the old trunions were intact.
I went to a couple shops, all were friendly and we're atleast willing to try. Seeing their presses though was like using a grenade to dig a hole in your front yard.
A few buddies said they had some rockers to replace my one scarred rocker, but they never came through. My local dealership with a small parts department had a new one in stock for $18 so I pick that one up
I work at autozone and we have a ball joint press that fit the bill. All of the old trunions came out easily without resistance. Be careful as you finish the old trunion will pop out and spill the needles

I know you already said that you weren't missing any needles as this is from a previous owner. I was just saying to count how many you pulled out of the pan and get a good count, then take one of your bearings you pressed out to do a quick check. That way if say a good bearing contains 30 needle bearing and you only found 28 in the bottom of the pan you could speculate that there may be 2 roller bearing still in the engine somewhere. Good quick fix on the ball joint press. When I do the CHE upgrade I think I am just going to go with a arbor press from hobo freight for like $30.

Very cool, car runs great and my old Futral noisy cam now seems silent. It's really strange not hearing any valve train noise, I had gotten so use to it that it always just seemed like it was part of the exhaust. Now if you stick your head under the car by the motor there is no ticking
Car seems to run alot smoother, but the big difference is not hearing any valve train noise, even the exhaust sounds different. It doesn't seem to echo the rattles out of the tail pipe anymore
