Not only is the Indy crossram MW port but it's got a HUGE plenum. If you run it on anything under 500", I'd put some fillers in it. If you want standard ports and are willing to do the work the modman can be a nice upgrade over a single 4 even with AFB's on it. I was at PRI and spoke with Chris at length with modifying the core to improve the intake. He was on-board to work in cooperation with the project but, I'm not sure I want to redo that this moment mainly because I have a few things going already.
