I have recently heard that someone here has done a dyno test with a Weiand square port intake on 427 oval port heads. Some have said it actually works good. Just wondering if anyone knows where I might be able to get those results?
Square port intakes on oval port heads works OK despite the big mismatch. The airflow will come through the center of the port. Not ideal by a long shot...but works.
This was the way everyone did it years ago when there really weren't any good oval port intakes. Now days you can get excellent ones. If you just had it laying around and wanted to use it...it will work. If you're buying something...get what fits.
