WOW! Let me by saying this manifold is a work of art. As you know I have an almost build motor in my garage and just received a manifold from Richwood Technologies and open it up. Its a Chrismas present delivered on September. This manifold is BEAUTIFUL. I immediately placed it on my engine and it fits like a glove. Everything clears and it slides right in. The only thing missing a twin screw supercharger. The plate I got was blank so I can put in any root style charger... If you guys have any further questions about this work art, please contact Richwood directly. Richwood not only sell supercharger manifolds but they also offer supercharger kit too. We have a very close working relationship with them and they will take care of our members. Here are some pictures.
