Well I just happened to visit the edelbrock website to see that they released the 4.6l 2v intake manifold. But typically you cant find a price and it will be a few months before we get real dyno results. I try and call edelbrock tomorrow but just letting you guys and gals know.


) with a Wieand Stealth dual-plane manifold. It's considered to be a "good" street intake manifold from idle to ~5500rpm. Its runners are lucky to be half as long as the runners on a stock 4.6 intake. In fact, from my limited experience it looks as though the 4.6 has the longest intake runner length of any V8 I've seen.
