I have a W5 intake, looks like the standard port M1 single.
I don’t suggest it. The Indy is far superior. Even with the height wacked down an inch, which is not a step in the right direction as far as power output goes. I get the fitting under the hood thing.
Pittsburgracer ported my M1 standard port intake. It did very well. The Victor is a better idea to use ported and slotting the bolt holes for use. Still, the ports of the Indy are different enough that making another intake work is not an easy task, if possible.
