Missed on this combo?
Not many intakes to chose from. Indy 360 is like hens teeth and needs a lot of mods. I love and have used an Airgap before, with a 1 inch spacer. I have seriously been considering that but I think that manifold is all done at 6000 RPM or so. They sure do make some torque, though.
What else is out there that can make power? Weiand X-cellerator? Come on now.....
