The intake manifold has the real restriction, when you look down in the intake divider floor there is a hole that is no bigger opening than the throttle body. Air going into the engine goes threw the throttle body to a hole that drops down to lower level a goes to the intake runners. The intake air changes directions many times before it gets to the intake valve. By removing the floor it becomes a big open plenum with long intake runners. In order to remove the floor you have to cut the bottom of the intake off then weld it back on. It is not a Saturday afternoon job. I got another intake from junk yard to modify but have yet to bolt it on. At that point another trip to the dyno to see the difference. Tom
