The flange also comes with an O-ring groove, and the top of the flange which sticks up for the three bolt throttle bodies has been trimmed off, giving more hood clearance.
The original manifold will continue to be sold as an LS1 XT, the new version is ccalled an LS2 XT.
Looking forward to more dyno result postings. Thanks to everyone for their interest and input. |
