Edelbrock Air-Gap intake reviews???
Is this crosswind the intake you had on your engine when you got coolant in the oil because you needed to use the cork end seals ??????
Back when this style of manifold was first introduced, Edelbrock ran ads in national magazines showing pictures of the then-new Air Gap. I don't remember the month for sure, but I THINK it was in the Spring. I contacted Summit, Jegs, and some other sources in an attenpt to buy one for my 5.9 Magnum, which was in the process of getting a blow-thru Vortec supercharger installed.
I had NO luck.... introduction of this manifold was delayed. I called Edelbrock on the phone and they cited casting problems for the delay, and said they were working on it and might be shipping manifolds in as little as two weeks. So, I waited. And after a month, I waited some more...
I REALLY wanted one of these manifolds! Car Craft, or maybe Hot Rod had gotten ahold of an early prototype, and tested it against some single-plane manifolds, and it was off, by only ONE horsepower in peak horsepower versus the BEST single plane, and kicked *** in the mid range.
So, by this time, the Professional Product manifolds WERE available (this was probably, October, by now) and I NEEDED a manifold, so I tried the Edelbrock option, but couldn't get one. That's how I ended up ordering the Chinese part.
I am running 10 pounds of boost, on an otherwise stock engine (except for a Hughes cam) and have had ZERO problems with this manifold.
I'll readily admit that I never checked it for core shift, or port alignment. Ten pounds of boost will cover a lot of misalignment problems.... :)
My car runs low-to mid 11's (3,300-pounds) and makes 445 RWHP, so it's kind of a fun street car.
If Edelbrock had gotten their act together a little sooner, I would have an American manifold on my car... but, they didn't.
Just thought I'd relay this story about a Professional Products manifold that has delivered a trouble-free service life, in spite of the bad press it seems to "enjoy." No water, oil, or vacuum leaks, so far.
