If the ports aren’t horribly undersized at the flange, I’m going to modify the one I pictured. The plenum wouldn’t be half the volume of a street dominator once opened. I have a friend that wants to put a four barrel on a stock 273. If the runner dividers aren’t a 1/4 inch thick, it may even have a chance of making more power than the stock 2 barrel intake. Design wise, it would be a 1/3 scale Weiand Xcellerator without the height. I’ll know how big of a steaming pile it is after I attack it with a hole saw and see what is after the plenum.
