very nice product

Great product, very nice chrome finish. Manufacturer does not make a mount for it, they suggest going to March Performance for the mount, but March says thier mount fits Delco, and this alternator is simular to Delco, but not quite exactly, therefore a Delco mount may not fit without modifying it.
Yes, I recommend this product.

Have had no problems with the battery whatsoever since I installed the 140 amp. alternator, but I fried one v-belt. Originally the v-belt would pull both alternator and power steering. Had to have one belt pulling only the alternator, as it is hard to rotate at full charging (and another one for the power steering).

These Silver Bullet alternators put out a whopping 140 amps max and still maintain 80 amps at idle. They are a single wire hook up with an internal regulator that sets charge rate according to battery condition. This should work with any electrical system and battery that are in good condition. If a battery is completely dead and it is hit with a high amp charge there is the possibility that the fast charge could cause the battery plates to sulfate and in turn damage the battery. In normal conditions there should be no problem and if running high current draw this would be the answer to satisfy the current demand.
