SOLD. Up forsale is a brand new ACDelco LS3 intake manifold modified for better flow. These modifications are similar to R. Crawford's intakes he did years ago.
I removed the three braces, epoxied nylon plugs into the floor, and use half round aluminum rods the entire length of the runners. The floor is sanded smooth. Will fit 92MM throttle bodies.
I've ran my first intake with the same mods on my 427 LS3 for two race seasons with great results. This intake will yield 10-18 whp depending on the engine it's being installed on. T-RM006 $575 shipped, $540 picked up. Thanks.

I would love to send you my nice used stock LS3 intake in exchange but I will be putting it on a set of Trick Flow 255 LS3 or WCCH Stage 2 L92 heads I have with a moderate boost street twin turbo setup probably pushing 18 lbs on E85. I am wondering if these will handle boost with the post removed. It is either this or a Fast which I have heard Sometimes have issues with boost also.

I have not seen a failure with the LS3 intake (posts removed) on a boosted setup. I have seen the FAST intakes fail under boost but quite a bit of boost applied. The LS3 is a single piece verse the mult-piece FAST.
