Intake manifold for 225 slant 6

I used a Bouchillon kickdown cable and a Hemi throttle cable (shortest one I could find) with a super six intake and air cleaner and a 2bbl Carter clone from China (the super six Carter had issues). Already had a 2.25 exhaust system. This setup improved drivability a lot, I think, particularly hill climbing and wide open throttle. It's hard to tell how it affected mileage, since I am tending to leadfoot it more by treating it as a small V8 rather than resigning myself to the slow lane. But I've taken it over Sierra passes and all around the NoCal backroads, and on extended freeway high speed jaunts on I5, and it's definitely a Good Thing all around.
