Is it a 2 bearing crank? If so is it a new steel one?
I had an initial problem with the crank touching the centre housing for the camshaft bearing.
The crank apparently whipped enough to take very fine slices of aluminium from the housing.
Another answer could be that if you fitted your old flywheel to a new crank that the taper was not lapped enough or the crank nut tightened up enough.
This makes quite a heavy noise.
