stuck (piston(s))?

[tgm_enterprizes]

My 1970 sedan has sat since forever but I was told by the guy I bought it from that it ran ok, just needed a battery.
Ok, I am a little gullible, but the car was a texas car that had never been hit and has only surface rust. Plus it was a 1 owner and was complete. It still has the original tires completely rotted, but still holding air.
Anyway, here is the things I found so far. The old style carb was corroded to the point that it was seized up. I pulled the intake manifold off and felt inside the ports to each cylinder and did feel some corrosion deposits on the roof of the passages, but it was not really that bad.
I put a late model carb on it and was going to see if it would run but have now found that one or both pistons are stuck in the cylinders. I pulled the plugs and can see the tops of the pistons and don't see much , if any corrosion on the piston tops, so I figure it's just a stuck top ring or so if I am lucky. I don't have a bore-scope so I can only see about 1/4 of the piston top.
I am looking for suggestions on my next move. I am thinking soak each cylinder with PB blaster and let sit for a day or two then see if rocking the car back and forth in 4th gear might free the engine up.
Does anyone have a better idea? (Other than a pull the head off type idea).

I just recently unstuck my coupe engine. It had only been sitting 8 years outside here in sometimes very wet Oregon. I removed the spark plugs and filled the cylinders with ATF type F. Let it soak for week, then gently started rocking the belt pulley by hand with gloves.....it just barely started to move, I kept at it for another week untill it turned free.

Does a Texas car mean lite rusting only?
Are the tires Bridgestone 5.20 bias ply?  Most unusual.
Patience is a virtue.  Take it slow and try to avoid breaking the rings.  Rolling the car in gear is a sure way to bust the rings.

Bruce,
My 72 N600 has the original bias ply tires on it. They've held air since I got the car about 4 or 5 years ago, in fact, I never have added air since then. The tread looks good. I drive the car about 50-100 miles a summer. Only 8,500 original miles on both the tires and the car.

ATF works good but Type F has an abrasive in it for Ford Transmissions to grip on. Probably not a good thing for your engine.
