I would love to see it vs the Action Plus. My experience has always been, if you pull one decent dual plane intake and install another, not much of a difference. Like the LD340. I pulled a TQ cast intake for one of these "ruby-sit on the throne" intakes. E.T. changed .1. Yes, 1 tenth of a second in the 1/4 mile on a mild 340/3.55 Duster. Did the same experiment on a 360 Dart/3.91's, gained that same tenth. Junkyard cast intake vs the polished diamond.....
I also this past summer pulled a TQ cast intake for the Holley Street Dominator, and so far the cast intake has run .08 quicker, 1 mph faster. Ironically, the SD cut a better 60 ft time. Very mild 318/2.76/auto stock converter.
