[QUOTE="e85svt, post: 16329185, member: 169360"] Most that go with a 4lb lower pulley are ported. Unless you run a fuel system and are on e85 I wouldn't add a lower pulley to your current upper. Though you could opt for a 2lb lower and pulley up. Full bolt ons with the 2.76 upper is right around the max (450-475) with an unported eaton. Any more boost and you start spinning it a little to fast thus creating heat. The 2.93 upper and 4lb lower is a very popular combo for ported blowers and can make anywhere from 500-525 rwhp.
