I take it you are talking about Phoenix. That missile is indeed BVR. But it was made to counter Bombers carrying nukes in cold war. It was very ineffective against fighters of past, forget targeting them today, I believe Iran is manufacturing some version of Phoenix? As far as i know it cannot be used in any plane other than F14, it was made to be used by a very specific radar. Granted the IAF in 60's was indeed very capable, but soon after the revolution there was a purge in military and a lot of very skilled pilots were lost.
