I am about to buy an alternator for my engine. It's a 360 stroked to a 408. Do I need an alternator with a single pulley or a double pulley? I plan on putting A/C on the car, which isn't stock. Do I need the double for the A/C?

 

Yes.

 

Are you sure? because since I bought my 74 fury 360 the alternator only has 1 polley

 

Do you have air?

 

Get the 2 pulley alt, should be a higher output

 

Yes, factory A/C and the alternator only has one pulley

 

Huh, okay. Still, can't hurt to get the one with two and, like Lynn said, it may have more amperage.
