I have a custom built intake manifold that was built by Aaron Miller (8Valves). It was never used. It has a "D" shaped 4 litre plenum with two hand crafted veloctiy tulips. I also drilled and tapped two 1/8"NPT threads for supplemental injection over each tulip. It already has an IAT sensor port drilled and tapped (I'll even through in the IAT sensor). It also has 3 (unsure of the thread) threads in the end of the plenum for vacuum supplies. The runners are mainly stocked but ported slightly in the upper regions.
It has been sand blasted and painted silver. This would surely help any 8 valve meet some outstanding goals.
Asking $300 shipped.
Thanks!
