It looks like another great combination from you guys. Just out of curiosity, do you have any knowledge as to why the torque and horsepower curve dip a little at 4,000 rpm? The rest of the curve looks very linear.

Its just the nature of this camshaft. If you look closely, its not a dip, it is just not increasing as much. It never actually decreases.

I can't say for sure, because we haven't tested any other intake manifolds. I can say that recent testing has shown that GM is on the ball with the latest intake manifolds (LS7) and it's probably pretty good out of the box. The only way to really step it up is the single plane. Intake flowed 330.

They are moving a larger volume of air in and out of the combustion chamber. Show me a engine dyno graph of an example.
