ls6 intake
i will be removing the intake, etc., in order to replace the oil pressure switch.
i am thinking of replacing the intake manifold. the LS6 manifold seems to be an obvious replacement. other suggestions are welcome.
will a LS6 manifold fit my 2000 C5? are there any modifications needed?
thanks!

If you go the LS6 route, if you look under the intake, there is manufacturing plastic under there (squares). You would need to take all that off so that the bottom of the intake is flat. Comes off pretty easily. Once that is done the intake will lay over the coolant tubes you have now routed under there. At that point, it is just a matter of swapping intakes.
Probably will want to get new intake gaskets. Probably a mess under there to clean up as well.

You can install the LS6 intake on your car without changing coolant tubes.

Remove any of the electronics (ie, MAP sensor), and the gaskets. I soaked mine in Dawn dish water for a day, and that got a lot of it out. I then went back with degreaser and sprayed and scrubbed, and that got the rest. It's nasty stuff in there for sure. Helps you appreciate the need for a catch can.

While there I would also replace the "intake valley cover" to the LS6 style---It is far superior as the PCV system on a LS1 allows tons of oil injestion into your intake manifold causing your fuel/air charge to be ontaminated
Just look inside your LS1 intake with the T-Body off and you'll see how full of oil the intake is--It's horrible-------This does require some mods to attach however but nothing too difficult
