In no particular order...yes, it's a race manifold. But it may have some use on certain street vehicles. I'd like to see some dyno numbers as well; it goes on my buddies car in a couple of weeks. The plenum volume should become apparent after the dyno and some track times.
Did anyone see the Trick Flow 2V manifold on page 36 of the December 5.0 Mustang and Super Fords? It's designed to work with PI heads, but mentions it can be adapted to work with NPI heads. MSRP is slated to be $799. A 5.4 version of the intake will be available in the summer of 2007. The 2V version is supposed to hit the streets in early 2007. We'll see!
