I NEED HELP WITH DRIVE TRAIN ISSUES I BELIEVE MY CLUTCH OR TRANSMISSION WAS IMPROPERLY INSTALLED

1968 Chevrolet Camaro

I just had an engine custom built. The block is a 1987+ 5.7L sbc 350 it is stroked to a 383 the transmission is a t56 6 speed manual the clutch is a centerforce dual friction clutch. I'm trying to rotate the crankshaft by hand to tdc in order to install the distributor. The crankshaft won't rotate even with a breaker bar and I'm afraid of snapping the bolt in the end of the crankshaft. I suspect that I must have installed the clutch or transmission incorrectly however I have never tried to rotate the crank while the motor and trans were not connected. As a sidenote the thing that makes me believe my clutch/trans is incorrectly installed is when I'm in neutral the car rolls freely however if the car is in gear and I have someone push the clutch in the car still won't roll. This leads me to believe the clutch isn't working properly.

I haven't yet installed the starter and the crank wont move at all.

So today I just backed out the bellhousing bolts and split the motor and trans apart. The crankshaft now spins freely. Do I have to bleed the lines for the throw out bearing? Is my problem in the slave cylinder? If so is there an adjustment I can make or would I have to replace it?

So basically my current situation is if I back the bellhousing bolts out the engine will turn over but if they're completely tightened down it won't turn over at all. My biggest misunderstanding is how the engine won't even turn over in neutral? Shouldn't the input shaft spin freely once the trans is in neutral?

THIS IS A GOOD ONE

SOMETHING IN THERE IS TOO BIG

JUST TO SEE IF IT'S BELL HOUSING RELATED

SPRAY PAINT THE INSIDE OF THE HOUSING WITH FLAT BLACK PAINT

GENTLY PLACE IT BACK ON (NOT SCRAPING OR SCRUBBING IT)

INSTALL THE BOLTS (OR A FEW OF THEM) JUST BARELY ENOUGH TO TO "INDEX IT" TO THE POSITION IT BELONGS (LOOSE ENOUGH SO THAT THE CRANK WILL TURN)

NEXT. HAVE SOMEONE TURN THE ENGINE OVER SEVERAL REVOLUTIONS WITH A WRENCH/ RATCHET

AT THE SAME TIME, "YOU" PUSH THE BELL HOUSING FORWARD WHILE THE CRANK IS TURNING

. SOMETHING SHOULD BE SCRAPING OR SCRUBBING ON THE INSIDE

REMOVE THE BELL HOUSING---LOOK FOR SCRAPED FLAT BLACK PAINT ON THE INSIDE. LOOK FOR PAINT PARTICLES ON THE CLUTCH STUFF

THIS MIGHT SHOW YOU WHAT TO INVESTIGATE AS BEING INSTALLED WRONG/ WRONG PARTS/ ETC
