Yeah, I don't see that as a good idea. I should be able to fully expose the discharge port to the manifold.I have seen a certain person do that (obstruct the port, in this case by nearly 50%) and the compressor basically fried...
I got some work done today. I cut a hole in the manifold to get a better look what I am dealing with.
Doing the angle cut will interfere with the 3&4 cylinder's runners. I have a rough line drawn about where the cut will land. It also shows the structures for the runners. I will be reducing the runner to open it up more. I don't think that will be that great of an issue as the other SC manifolds as well as the pre 2000 manifolds had a great difference in the intake runner length as the log portion of the manifolds is part of the runner length.
This is the currently intended cut.
I am considering having a box welded on the underside to increase plenum volume since I will be taking so much away. Also, I will be putting 1/2" strips under where the bolts will land. I don't like the idea of running a bolt into 3/8" aluminum only. They strips will be held in by aluminum body panel adhesive or JB weld. I need to look up the technical specs of each to see what kind of heat they can hold up to. With the 1/2" strips and the 3/8" aluminum plate I may be able to use fredserts instead of tapping into the bare aluminum. http://www.fredsert.com/fred2/index.html. If I still don't have enough depth I may just bolt into the aluminum and at a later time, if necessary, use keenserts as suggested by o-gauge. I also haven't looked into the cost of fredserts, but I fear I may get sticker shock from the serts and tooling costs. The word "milspec" comes at a high cost.
On the vacuum ports the brake booster will get its own port as will the PCV line. For the three vacuum lines on the side of the manifold (emissions, and cruise, etc) I am thinking about doing a distribution block with a single large line coming off the back of the SC.
