The Autozone battery should be called Duracrap. I bought one in Oct and it does not have a lot of reserve. It's really light, should be much heavier for 900 CCA. Also a lot of money (about $90 now). I was able to get all of my money back and went to Walmart and bought one for $64. The Walmart battery feels heavier and comes with a 2 year free replacement warranty. I'll have to see how it holds up.

The Duralast has a free 2 year replacement as well.

Quick Update-

I received the alternator yesterday. I put it on last night. It was pretty straightforward. The hardest part ended up being the new wiring. It bolted in and the belts went on fairly simple. It came with a double pulley on it already. As others have stated, the Eagle Auto guy was helpful and he has sent me a couple messages making sure I got it and that it is working.

I bought 2 premade 2 gauge cables. The first runs from the alternator to the battery positive terminal. I also spliced the old wires to the alternator and hooked them up as well so they still go to the junction box. Then I figured while I was at it I might as well upgrade the wiring to the starter. I added a 2 gauge wire from the starter to the positive battery terminal so I have as much current as possible going to the starter. Overkill I know, we will see if it makes a difference.

Now really the only thing left to do is add a cable from the engine to the negative battery terminal to make sure the engine is grounded as best as possible. Again, overkill.

I got 14.1 volts at idle with nothing turned on. I didn't check it with everything running.

Thanks for your help.

yeah, but the walmart batterys have a 3 year replacement warranty!
how many times in that 3 years you will have to use the warranty is up to debate... bummer.
what walmart battery are you using?
I could only find group 39 batteries that fit in the MB spot... kinda dinky IMHO...
the larger batteries from walmart are too tall and have the terminals on the wrong side...

I don't like the ground strap either. I got stranded for a day after doing a bunch of 0-60 time trials. Starter clicked but no start. Battery was good. Turned out the bell housing bolt for the ground strap worked itself loose enough to not provide enough current to the starter. There was only one bolt on the starter, and one other bell housing bolt of the wrong size and that was loose, the other engine to transmission bolts were missing. This was probably from the shoddy work of the place that rebuilt the transmission (PO did that)..Point of all this is if the ground strap went from the starter direct to the battery, I wouldn't have been stranded.
