For less fuss, I'd remove your present bad alternator and take it to the auto parts store. Get it tested there to be sure it is bad. Then buy the exact same style and part number that you currently have. Do you need more amps? If not, buy the same part number.

Well I actually had to pull the alternator out of my camaro to put in my wife's firebird lol. But what I am wondering is putting a higher amp alternator in the car a bad idea? Basically is there an upgrade I should do do now? I am putting the new alternator in my camaro.

Use a truck alternator. It is 145 amp and gives much more stable volts. From 99-04 trucks at a junk yard for $75 and will be identified as KG3 truck alternator
Refer to my alternator thread, if you buy a replacement alternator you'll regret it.
Use a truck alternator like mentioned above, the 145 amp. Hell the 105 probably be fine but why not go 145. You'll be happy if you do. There's a reason this thread is 50 pages long, it's all positive feedback after people do it.

Put a used truck alternator in it and be done. I went through 4 new/ reman then put my 280,000 truck alternator in and never had another issue. Then I went to the salvage yard and got another one for the truck lol.

It all comes down to the creature/feature comfort accessories you have on your car. The more accessories, the higher amps required.

10 Camaros You Should Never Buy
Very true. And also look at it this way, with a high amp alternator you're taxing it less for a given amperage. For example the stock alternator runs around 50-80% of it's max capability at all times with all stock electrical (depending on how much you have turned on and if the fans are running), the 145 amp truck alternator will run about 30-50% of it's max with stock electrical so it's way happier.
Same here. I went through 10 and it's what led me to find the cure and make that alternator thread. I got a truck after the camaro and one of the first things I did on it was a 145 amp junk yard alt on it too.
