Sounds like you spun a main. Every lt1 ive torn apart the has locked up has always spun a 3rd rear main i dunno why. But usually when it spins a main it will wedge the crank where it wond turn over. Did you rebuild this motor yourself or have some else do it? if its your original block what was wrong with it b4 the build?

If your cylinders have fluid in them (antifreeze) then you will not be able to turn it over, and dont try it with the starter unless you want piston and or rod damage, pull the plugs, turn it over by hand and see if any fluid comes out...

Very true if it hydra locked definetly take the plugs out. another thing, is if you had spun a bearing and ruined a crank, it you tear it the rest of the way down and send the block off to see if it needed line bored? Chances are if you had that much destruction youll prolly need at least line honed to true it up.

when you say "i got all that replaced"...what exactly was replaced? theres a lot of components that will fail due to spun bearings...the crank and main bearings are just the two most well-known parts. if there was metal shavings in the oil...chances are you needed the block tanked...IMO

I vote a blown head gasket, or a non properly installed gasket led to anti freeze in the cyl which lead to the hydro lock

oil was very clen no metal shavings none zip zero nada
