Another thing I'll point out is that the Indy manifold was really rough out of the box. We tried it on the dyno and it didn't work very well so we went back to a Wilson ported standard port intake. I had my Indy manifold reworked by Wilson and then the motor started to make some serious steam. The out of the box Indy intake killed a bunch of power on my engine so that is something to keep an eye on.
