Finally got my coil sorted out and got the engine running.
1998 350 Mag MPI serial 0L009914, with VelvetDrive 72C gear
It has a miss. It is not as obvious as miss like when you have one dead cylinder. I have checked all spark plug wires, and with timing light on each wire i can see rhythmic flashes without any visible anomalies. When I point the timing light at the crank pulley timing mark, I can see the timing steady at about 8 BTDC, and every 3-4 seconds timing would move few degrees closer towards TDC mark, and then go back to about 8 BTDC. I can also feel with my hand on the motor that its skipping a beat every few seconds.
Engine has new correct spark plugs with correct gap, new spark plug wires, new cap and rotor, new coil, all new injectors, etc.
Here is video of the engine idling, not sure if you can make out the missing sound and/or vibration?
Thanks for all the help!
