Alright I did a search but still dont know. I wanna get rid of my old weak alt and go with something thats gonna compliment all the new MSD ignition stuff I just put on. There's a huge jump in price between 100 and 130-140 amp alts, so I dont know is it worth it for a 140? I got my eye on this one , but it says its the 2g style case, which is and old design from what I hear. any help would be appreciated
