130A Alternator DIES every 2-3 months

[nightmare95stang]

I have a 1990 mustang pulley setup on my 95 mustang. I also have a supercharger drive crank pulley, 4 inch accessory and 8 inch blower drive.

I did a 331 stroker motor swap in May, and I bought a new 130A alternator for it, and it died 2 months later. I replaced it with a new one, and it just died again this past week (3 months later).

Does anyone have ANY insight on this? Are the electronics I am running a bit much where they would zap these new alternators so quickly???
-9 autometer gauges
-Flex-a-lite dual fans (set to go on at 180 degrees)
-MSD box
-basically stock fuel system with a 255 in-tank pump and a Vortech T-rex external pump
-42 lb injectors and matching MAF

Could it be this, or could it be that the engine's extra heat causing the alternators to die? I noticed a marked higher difference in temperature when I held my hand over a just turned off 331 engine than the 302.

Any help?? Anyone!!
