Dart intakes? Are they good pieces to use or stay with Edelbrock? Just noticed they have a Kool Can intake very similar to the Air Gap intake. Same or?

I really like the Kool can..cheaper than the air gap too

I run the cool can on my 70 and have had good luck with it. The machine shop I go through has a deal with Dart and he recommended the intake. I can't say it is better than the air-gap, but it seems comparable.
