Dyno'd the Magnum.

The real Air Gap is worth a ton over the knockoff. My experience is only with the LA intake, but they're probably both the same.

The real problems is that edelbrock is to damn greedy to give us a dual bolt pattern manifold.

I have the "knockoff" air gap because i had an LA and knew i'd be going magnum if it ever blew.(which it did).

I would have bought an edelbrock without a doubt if it had the dual bolt pattern. :thumbdow:
