414 Dyno results: Missed combo?

I took the opportunity to do some really rare and cool air cleaner testing with this engine it was so consistent. A friend of mine is obsessed with finding more efficiency with his small Chevy and purchased the entire R2C air cleaner set with interchangeable center sections--like the old K&N stub stack. Yes I flow tested all of them and of course the highest flowing assembly did NOT result in the most power. J.Rob
