I have one on my 360. I can't tell you how it performs compared to the Edelbrock Air-Gap but it works well on my 360. The engine is making about 370 HP with it and runs strong between 1500 and 6500 rpm.
Contrary to what the naysayers will tell you it is not a knock off of the Air-Gap. It does have the open area under the plenum like the Air-Gap but other than that it is a different as two intakes of the same type for the same engine can be. I couple of months back I was parked next to a Duster at a show that had an Air-Gap and the Crosswind actually has a better finish to the cast surfaces than the Air Gap.
thanks that is what i wanted to know not extremely worried about how much power it actually makes just want to make sure the casting is cleaned up and it fit nice no alignment issues i really just want to get that heavy a$$ cast iron intake off there and replace it with something that looks nice and performs well and will not break the bank plus i may go with magnum heads in the future and it will be nice not to have to buy another intake Thanks Justin
