Seems like amperage is like money.(there's NEVER enough).
I bought a Powermaster rated @90A and still loose a little ground @idle. Of course my load combined is 46 amps and I have an underdrive pulley. The alt has been measured @ 90 amps when the engine revs some. In your case the under drive may be the reason you still have a idle issue.. if you had the stock rpm ratio it would most likely take care of it.. they still need to turn X rpms at idle to have a positive output(that will exceed your total draw) EDIT I can see a fluctuation at idle if the fan kicks on and it has a rpm drop(before the AIS kicks it back up so that can last maybe a second

How much do these Toyota alternators weigh?

I checked the 14611 on the bag, $63 so not a bad price. It looked like all of them were set up for a ribbed belt. Where can you get the correct pulley? I made my pulley but I'm sure that someone sells the pulley... I wanted a deep pulley

How much do these Toyota alternators weigh? Well I'm at work here in the Toyota shop and I just threw a pick-up alternator on the scale and it weighs almost 10 pounds. Some are lighter but this one is a 90 amp 2000 Tacoma alternator. Gus

So does this alternator have the balls to run an EFI pump, HHR fan, electronic ignition as well as lights, etc. ?? If not, what sort of amps would it take?

Well new cars have all of that and more and the OEM engineers don't seem to have any problems putting these Denso alternators on new cars. My wife's 4Runner even has heated seats and stuff like that which you aren't going to find in any muscle car.

I ran an HHR fan,electric water pump,fuel pump, lights,and my MSD ignition and the volts dropped to 13.5 at 900 RPM with the brakes on at a light. That was with the 60 amp unit that I pulled of a cash for clunkers car 8 years ago. This conversion is the best update you can do for your car. Just imagine sitting at a light and your head lights don't dim like a pee-hole in a snow bank. The one thing I do strongly suggest is that you go with a factory Denso re-man unit over a P.O.S. Ebay junker. I have never had a problem with Denso rebuilt parts but I have seen dozens of cheapo re-builds crap out or not work at all. Gus

Mine`s a v-belt from Kragens and would rather buy locally w/a warranty than on line but that`s just me........... Same here, I had one go out and got a free replacement from autozone. The first one only lasted about 8k but maybe it's due to the 6,500rpm shifts or heat.

if you can deal with only 60 amps then look up the part number for something like an 85 toyota pickup, it will have a v groove pulley.
rockauto is a good place to get the part number.
