More small parts ordered:
NST 10% overdrive alternator pully - help offset some of the alternator RPM loss from my stillen underdrive crank pulley. Easy, light, cheap, might save me some headaches some days.
Elite Engineering C6 Catch Can - This is made for 'vettes, but really the only reason it's considered a vette part is because they ship a mounting bracket that mounts onto LSx engines easily. I had this can on my LS1 Trans Am for a long time, was really impressed with the quality of it (the mesh/outlet design, ease of dumping the fluid, etc).
With the way the PCV hoses are set up on the M370 Manifold, you now have a single, combined PCV hose (T-adapter from both valve covers, single run to rear of intake manifold), making it easy to use a single oil catch can for our car. Since I relocated my battery, and since oil catch cans work better when they're a little cooler than the rest of the engine bay anyways, I'm going to figure out how to mount this thing in my empty battery compartment.
