79 cherokee chief

So I got a 79 cherokee chief from my uncle he started building it back in the 90s and just never finished it and wants to seem it finished so now I have it. The motor is a 360 bored 30 over and cammed but it hasn't ran since rebuilt 20 years ago. I tried turning it over by hand but no go. I pulled the plugs and soaked the cylinders with some penatrating oil and letting it sit are there any other tips to help me get it turned over? It was also a frame off resto so the frame and floor are all sand blasted and rubber coated if there are any tips that would help me with this project please let me know. Thanks here are a few pics of it im determined to get it going and im aware of the amount of time I will have to invest in it.

Automatic transmission fluid in the cylinders and a good heat lamp on each side of the block. We loosened a '55 Ford six that had been sitting from 1979 till 2010 that way.

Couldn't hurt at all. Seen a few engines preserved by filling 'em almost full of trans fluid. It's pretty versatile stuff. I use it as a lead substitute in my '55 Chevy truck too. Bonus: it keeps the carb clean along with everything else. Just "cheap" Dexron is all you need, has the least friction modifiers in it.

Ok sounds good ill drain the 20 year old oil out and fill it wit trans the motor pretty much went from the shop where it was built to the jeep where it sat the pistons didnt even have carbon on em thats probably the worst thing u can do to a fresh engine is let it sit that long ive also been told kerosene works wonders to.)

Yeah, kerosine is a fuel oil, it lubricates almost as well as it cleans. It's the main ingredient in engine flush too. Rinsed my entire rear diff in it when I rebuilt it last month, came out clean as could be with a little scrubbing inside and out, and didn't hurt what was left of the paint.

if the engine was sitting for 20 years without having been prepped, you've probably got a bit of work ahead of you. I'd pull the heads and get a look.

drop the pan and get a look too, i'd hate to see what everything looks like under there.

Always a good idea, and if you're feeling really ambitious, don't be afraid to pull the heads for a peek too.

Ok so a week went by with me dying inside to mess with it but i needed to let it soak in pb blaster i tried today still no luck but i was bored so pulled the passenger side head off it came apart like butter no effort at i was amazed but wheb i got the head off i was alittle scared with the. Amount of rust in the cylinders but i tapped each piston with a small piece of work and she moved!! So i worked it back and forth slow wiping the rust out and spraying more pb in now it makes a full turn man that made my day to see it turn it was pretty discouraging after pulling the head off and seeing it.

So i got everything cleaned up on the chief and got a nice deal on an edelbrock intake manifold for 75 bucks for it but before any of that i drained the 22 year old oil out and well i got about 2 quarts of water out of the oil pan. I guess when it rains it pours lol the motor is free and turns over and the cylinders are nice after i re honed them. I have to pull the oil pan and check it out more before trying to start it. I hate to change the factory intake and carb but my uncle has a golden eagle all original and hes having issues with the car so i wanna make it more driveable that and with it being bored out to a 392 and cammed as big as it could go back in 1990 it needs to breathe more so a nice intake and 4 barrel carb and maybe a set of long tube headers. I plan on showing the jeep i dont want to beat it in the woods or anything just take it to shows for people to appreciate it.
