I already pitched that one at #7. Fair bet there has been a near sudden loss of mechanical drive somewhere between the CBOX output and the MGB input and the engine squealed because it wasn't very happy about. Another possibility is a TCU or PT governor issue (it's happened before, sudden loss of engine power due to improper rigging or worn components in both governors or the TCU). Whatever the cause I'm sure they'll work out what went wrong soon enough.
