Brian, It is the stock parallel valve IO-360 vertical up draft. The same style sump that I used on the flow bench for initial testing. Engine testing on 01/23/2010 will be on the same type of sump with stock and modified induction tubes. We will test 5 to 8 different configurations with the different intake mods. Depending on what config. works the best, might well work with your cold air system also. I prefer not to project the power gains publicly at this time. However, 7 years ago I did similar mods. to a 3.0 liter V6 Toyota engine and produced close to 8% more power @ 100% throttle (comparing, Apples & Oranges here though). The results will be up as soon as possible on the group wall.
