Again lost in translation is what happens so often when giving the interview over the phone. When I baselined the unported manifold 230cfm is all that it could support. The manifold was highly ported and I had welded runner extensions into the plenum in an attempt to best the 510-513 ft/lbs I was seeing prior to the runner extensions--it didn't work and I cut them out little by little until I got back almost to where I started. The trickest part of the manifold was the .250" thick Teflon intake gaskets and the heat shield welded to the bottom of the intake. J.Rob
