From what I have seen when cost is not a deciding factor auto makers / tuners tend to go favout air horns projecting into an ample plenum as opposed to the "log" manifold.  With the injectors pointing into the air horns low speed trottle response and idle is going to be less then optimum however mid / high speed performance should be good. -- Ian

 
Hi Ian,
 
That's interesting, and makes sense.  I already have the primaries in the intermediate housing, so I can just leave those where they're at, and it will take care of the low throttle operation problems.  The secondaries will just be for high throttle, which should work fine if pointed into the bell mouth.  Still, it might be just as easy to install the secondaries in the runner that goes to the engine anyway.  Just kinda testing all the options now. 
 
Cheers,
Rusty
