[QUOTE="Comp281, post: 14738716, member: 79925"] If you don't want to install an additional pulley to eliminate belt slip, just go with a 3.0 upper pulley. Going all the way down to a 2.76 on a stock eaton isn't necessary because it lacks efficiency at that point. I've always done a 3.0 and made 460-470 rwhp with the factory pulley cover on and no belt slip. I have always done an aftermarket intake, TB, and exhaust - just to be clear about the mod list at that hp level. I've had 3 cars set up that way. The 2.76 will make more heat and not much more hp.
