Impact of the Fast Intakes on past and future cam design Im wondering what the affects of these new intakes will have on past and future cam design. This is in regards to a stock displacement car, cam only or h/c car. What do you cam guru's think. Should people hold off on cam selection?

I did some computer modeling of various head configurations, using my database of port volumes and cfm numbers, and this intake has an greater impact on the small cross section heads more than the larger ones. I believe the latest dyno testing has shown this to be accurate though I have no information on the heads used.
As per one model, the AFR 205 with its small volume intake runner with tremendous velocity, responded well to the intake whereas some of the larger runner heads showed a smaller pecentage gain. The LS6 pieces also showed better results (percentage-wise) than expected and all combinations showed a positive number.
Remember, this is a "computer" model and not the real world. It's been pretty damned accurate on the cam profiles I do, so I trust the results.
