Recently purchased a 1978 k5 blazer. Has a 350 and a th350. Transmission was leaking from the pan. Come to find out none of the bolts were tight. So I dropped the pan and replaced the gasket. I made a rookie mistake and overfilled the tranny. So I started back from square one. Now tranny is full!! But it won't grab any gears. Once I out the truck back in park it makes a grinding noise as if I'm rolling them slam it into park

Double check that the tcase is in gear and not partially engaged.
Another vote for t case being in neutral.
I'm gonna pretend I never posted this!!
Don't feel bad. Our work trucks have manual transfer cases and guys regularly prank each-other by putting the t-case in neutral. I've seen more than a couple trucks hauled off to the auto shop behind a tow truck over it when no one figured it out.
I wonder what the guys at the auto shop say when another one rolls in with the t-case in neutral LOL!

I put the 4x4 into gear. Now it engages but the truck still doesn't move
203 transfer case?
Run it in neutral for a bit to fill the trans back up. Possible issue with the filter install and it's sucking air. How much fluid did you end up using to fill it?
6 quarts
YER TRANS BURNED UP?
No issues until I changed the fluids. I drove the truck for about 10 minutes when I bought it. Then drove it around the block once I got it home. Shifted just fine. I only dropped the pan due to the leak. Which was due to the guy not tightening the pan bolts
I was thinking the same. I bet the trans or torque converter is shot and the trans fluid change did it in. I swapped out a TH400 once upon a time and didn't change the torque converter and I drove it about 5 miles and then it acted like it kicked into neutral and that was it until I changed the converter.
Someone will probably chime in and tell me I'm wrong, but the shift rails in the Tcase itself are probably binding.Also all 78 k5's that I have seen have NP203 transfer cases.You sure it's a 205?Hope you get it fixed.
I meant to say that all 78 k5's from the FACTORY that I have seen have had NP203's.If indeed the Tcase is 205, the shift rails themselves are pretty easy to take out and inspect . Of course before you do that , check your shifter.The shift rails on a 205 can be removed by taking out the "poppet" screws/ springs/ balls on the top of the case. There are two. Use a pen magnet to get the ball out after the screw/ spring has been removed. The shift rails should be able to then be removed.
I'm gonna crawl under it in the morning and double check the transfer case
