Save the time and drop the pan and check the main and rod bearings. Pull the supercharger and check the gears and bearings in there. Why pull the motor when you have no clue as to whats wrong with it???? Check the alternator, that will squeel if its bad. If the alternator is not putting out, the car will run for a short time untill the battery goes down and the car will quit. I have never been deep into one of these motors, but I need to know whats wrong before I pull a motor. But thats just me. Good luck!!
