Reminds me of the time a buddy of mine had a nice 2nd gen Trans Am that his wife drove he came home one day and she told him the engine was making noise,he checks and sounds like a rod knocking,he decided it was a good reason to upgrade to a built 455 and proceeds to do so,while pulling the low mileage well built 400 he notices a big dent in the oil pan,his wife admitted she had run over something in the road and that was when the noise started.It was amazing the racket it made when after pulling the pan witness marks showed the rod was barely kissing the pan.
348 stuck..

Nothing that old or extensive, however in 1988 I bought my wife an 88 Formula Firebird. Bright red don't you know. It still basically had no miles on it. So one day I was going to take it somewhere. Started it up, and turned it off. Asked her how long it had been making that noise. She said a couple of days. PCV valve stuck open. Sucked out 3 quarts of oil. 
Luckily I just added the oil and it ran fine the whole time we owned it

My pan is a little 'flat', maybe, that would be nice..

I've sprayed in Gibbs, a fair bit, and moved it, still only an inch or so, but I cn hear it 'squishing' past the loose plugs, so its moving. Seems odd I can move it at all if there's rust in the bores. I'm gonna pull the rockers off, eliminate all that stuff, and poss the pan (in case the cranks hitting) see what happens. Thanks for all your insight, much appreciated.
I always put two long bolts on the flywheel flange and use a 6' bar and work it back and forth little by little. That really only works though if you feel you have a chance in hell it will come loose. Keep in mind that if you have more than 2 cylinders stuck you probably want to stop wasting time and pull the whole thing apart.
This borescope is what I use to check rifle bores and inside of jackets when core seating bullets. It allows you to look straight in or 90 degrees. There are cheaper alternatives out there if you're not using them often.

Pulled the rockers and dropped the sump today, still stuck. How much force should i be applying? Ive made a little adapter that bolts to the balancer via the 3 pulley bolts that i have a 1' wrench on, but with the mention of a 6' bar, maybe I haven't got enough leverage??
I remember when I was pretty young my dad had a stuck 283 he let soak for a long time. He also made an adapter to bolt on the balancer so he could put more leverage on it. He put enough effort into it that he split the balancer in the keyway. Don’t know if yours is that stuck but it’s something to keep in mind.
If you can pry on the flywheel teeth you'll get a lot more leverage than up front.
I also would try with the flywheel not the balancer.

I am glad you got that motor turning. I think that you were fighting yourself though. An extension on a flywheel turning tool on the flywheel would have given you exponentially much more leverage than turning it from the center of the crank. Like stroking and engine, you move the away from the centerline. Still, the important part is it is turning, good luck.
