My alternators already have slight "underdrive" pulleys compared to stock. I now have "320" amp and "370" amp hairpin Singer alternators on my truck. I idle around 500 rpm and my truck shifts around 2k.
Does anyone know where I can get an "overdrive" crank pulley for a 2007 Silverado Classic 1500 with the 5.3? I've seen overdrive crank pulleys on other vehicles with superchargers, and was wondering if I could get an overdrive pulley for my truck.
I saw one mentioned on a GM trucks forum that was 10% bigger, but all the links were dead :/
