v8 alternator swap

i am adding extra load to my car and i remember that there was a nearly bolt on upgrade off a Caddy - can't remember which one - I believe it was a Bosch unit - can anybody let me know the origins and then i can look up the part and specs - have a larger unit that will put out a whopping amount of power - but have to mod the housing so if there ever a failure it could be a issue

While the Cadillac Catera alternator has more output, the conversion is not so much to increase the output as it is to gain reliability and easy availability (and save a little money). If you are significantly increasing the load on your electrical system you must also consider the wiring, the battery, over-current protection, and other things besides just putting a bigger alternator on. While you won't have to modify the car to use the Catera alternator, I wouldn't call it a bolt-on installation. You need to modify the alternator a bit and to get it into position you need to lift the motor.
