INDY 'modman' 2x4 intake. How much would you spend if...

Pardon my interruption lol.
I think readily available tunnel ram option is only the wieand and from my experience with the wieand design is incorrect from the start. They have a reverse taper in them, small at the top bigger at the bottom. That's the reason I had put so much work into mine & the end result looked more like an M1 / Indy tunnel ram compared to a D shaped runner entrance that changed into a rectangle.
I think Sean's mod man will blow everything away that can be purchased of the shelf.

Thanks! There are a few things I'd do different if ever again. Two main things are making the lid to accommodate some 4150's and then flipping the spacer 'inside-out' with the scallops in the inside to 1)allow more volume 2) allow a radius at the roof entrance. One thing to keep in mind is the best intake will be designed around the entire engine application for runner length and cross-section and plenum volume. This was set to peak just above 7000 on its 486" Indy SR-head motor. 275@ 050 .735" lift 110 lsa
