Is that the replacement for rebuild pellets.
I can't remember if it was 2 or 3 pellets per cylinder.
That can would sure make it easier. lol

In the 2nd pic, it kind of looks like a chunk is broken out of the edge of the piston. Of course, I've never been good at identifying ink blot pics either!
That’s what I thought. But the other pictures look like it’s some kind of trash.

Ink blots and magic 8 balls…neither playing nicely with me. I wasn’t able to tell, tried to get a poke and the black oil globs were hardened. Definitely could be coming out from piston damage, no idea.
Hard to tell and eventually ran out of time to experiment. I’m sure I’ll go back and look at some point while I’m waiting to get it back on the road
I haven't forgotten. I still use non detergent oil. So should anyone who runs a flat tappet camshaft. Either low or non detergent.
Is the engine back running? If so, run it at high idle and revving it higher and slowly dribble a bottle of water through the carburetor. That will break up those carbon chunks in that cylinder. You can also use seafoam. It will smoke the neighborhood out but that will probably fix it.

It runs pretty decent, if it didn’t cost me 15 dollars in disappearing oil every time I drive it it’s probably be fine as is. I’ll give that a shot today and take another look. Couldnt hurt at this point.
Already smoking out the neighborhood and anyone driving behind me half the time.

With how they were looking they would make some sense.
Obviously your valve seals are nonexistent. You could install new Viton positive valve seals. You could also bring the piston to TDC and get a drill bit the Minor diameter just a smidge smaller to fit through the spark plug threaded hole. Then turn by hand just enough to break up that carbon lump. Clean with a shop vac to get as much carbon out of the cylinder as you can. Run Valvoline 20w50 racing oil with a good filter. What intake manifold gaskets are you running? This also could be an exercise in futility, but it would be a last ditch attempt to keep it running while you line up a replacement.
My brother had a 340 that was sucking oil out of the lifter valley at the bottoms of the intake ports due to bad seal of the intake gaskets after an intake swap. We always put some silicone sealer around the gaskets at the bottom of the intake ports on all intake installs after that, just in case.

Cleaned up cylinders because...well, i dunno anymore. Something to do?! Reading through some threads, checking around on marketplace/craiglist/ebay and doing some "Im not the best at math" napkin math. Here is where I'm at.
5.2 swap:
- Rebuilt shortblock for $1-2k. another $1.2k for heads (ouch!). $500 intake. $500...for something else i already forgot...and some other bits and pieces could find myself sitting at 5k+ and at that point might be better off buying a different engine entirely. Seems like I can keep a lot of the 273 pullies/covers and parts though.
-A few used/junkyard 5.2 runners can be had for about $2k here. Would also need some parts but I'm worried this could take me back to square 1 and i install a used engine that ends up with the same problems and also needs a rebuild.
With these options, should I just start looking for other 318, 340, or 360 engines? Looking to keep the push button 904 trans which is an early version and sounds like it will create some limitations.
Considering that magnum pretty hard if I can find one, re-use what I can from the 273. From the swap threads it seems like there is a difference in power steering locations between some 5.2s. A couple other small hurdles but starting to feel doable.

your math here is a little wonky.
reman 5.2 long blocks are about 2500, hong kong phooey intake is 150, re-use your carb. you'll need a new oil pan & pick up but that's pickles.
so you'd probably be all in at about 3K
or roll some dice on something like this:
don't discount anything. a deal is a deal if the parts are good. they'll all work in on way or another.
