Here's a fun one, when I was working with David Nickens on the MOPAR program, most of the teams had covers on the intake manifold to keep anyone from even getting a clue about plenum size, runner length, etc. We never covered anything. And those in the Pro Stock "Know" would often shake their head looking at our manifold, HUGE plenum and extremely short runners compared to what everyone knew was the way to go.
What they could see was that yes, we had the manifolds built like that, but then we filled them with epoxy and machined the inside to what we wanted. We could take one manifold, try six different runners and plenums and when we were done, fill it up with epoxy and start over. Instead of buying 10 manifolds to try things, we just kept grinding out, then re-adding epoxy untl we got what we wanted.
I know of one team that had an aluminum (I think it was actually cast not billet) valley tray and various plenums but used composite runners. They could cut and glue until they got the magic combo, again without having to buy or make 15 manifolds.
