I'm in the process of building a supercharged 408 LQ9 and need some advice on what intake manifold to run. I plan on running 18lbs of boost with a Vortech Ysi supercharger. My cylinder heads are PRC 237cc. i was originally looking at the Fast 102 but heard that they are known to come apart at 15+lbs of boost.

That totally isn't true about the Fast 102. I have ran my Fast 90 at 18 psi with no problems at all and the Fast 102 is built better than a Fast 90. So if I were you I would run a Fast 102.
