it depends where you get the alt. I got mine from autozone and the pully that came on it was huge. I swapped it out for the one on my old alt. I had to have about .125 milled of the back of the old pully yo fit the new alt. Now I have full charge at 600 rpm.

all you need is a new wire harness. You shouldnt use the same one (fire). I found mine at 50resto.com. Get the power wire too. It reduses the noise a little. Good luck.

You'll need a smaller pulley if you run underdrive and electric fan, like Bootsy said. Really if you run underdrive at all - I have a manual trans and when I didn't run a smaller pulley I would stall the engine if I tried to ease out of a light without giving it some gas. It's being a little lazy, but the voltage would drop so low that I'd lose the spark.
I'm not afraid to give her some gas , but I love knowing that I have enough torque to start rolling at an idle.

some 3g alternators have a large pully, and some have a small pully. If yours has the same pully dia. as your stocker than you should be ok.
