I don't know what size that alternator is for Andy's bracket. Look up the dimensions for a GM CS130 alternator. They are 105 amp I believe. I run one and with a 5" crank pulley it charges great! I run two fuel pumps, electric water pump, two electric fans, a third fan on my fuel cooler, EFI, lights wipers, headlights, it can run them all and maintain 14.2 or so even at idle. At the track my voltage might move .1 during a pass max. It is one of the best changes I have made to the car.

I let my EFI run everything it can, water pump, fans, fuel pumps, whatever I can let it run I do. The only button I have that isn't run through the computer is my line lock. I went from a bank of switches to nothing but a key, line lock button, and a starter button and I love it that way.
