Dan will obviously weigh in with a much more educated opinion.   But I can 
say that when we dynoed my 408 stroker with numerous different intakes, 
including this one, that it performed exceptionally well until about 5000 rpm or 
so, at which point performance tailored off.   But it had the meatiest 
torque numbers below 5000 of any intake we tested (going from memory here; Dan 
will certainly provide the actual data and correct that assertion slightly).

It seems that the Air Gap is a great place to start.   I don't know if 
porting it will hurt the bottom end in exchange for greater high-end 
performance.   But if you don't plan to be ripping around at high rpm, leaving it alone 
might provide the best solution?
