the high output alternator would blow up my battery... is that true?

No. A high output alternator only puts out high current when there is a demand for that current. Most of the time it's only putting out 30 amps or so, just enough to keep the ignition powered, (plus computer and fuel pump on EFI rigs), and the radio. It doesn't take the battery long to recharge from the current drawn from it when starting the engine.
The voltage regulator controls the output current of the alternator. As voltage drops, the regulator tells the alternator to supply more current, to keep the voltage right around 13.6-13.8 volts. As the load increases, more current is required to maintain the voltage. If the load exceeds the capability of the alternator to provide current, then the voltage will begin to drop, as there isn't anything else that the alternator can do at that point.
So you threw out a very desirable 140 amp police special alternator. /forums/images/graemlins/frown.gif
