Are the lifters clacking from lack of oil? If not, your push rods are probably plugged.

Have you put an actual mechanical gauge on the oil pressure port at the front of the engine to check pressure? wouldnt be a bad idea.

Spin the oil pump drive-shaft counter-clockwise to prime the motor.

whats your oil pressure reading?

Do you have the proper plug in the rear oil passage(its inside the motor, behind one of the plug/cap inside the bellhousing area.
