That's a high RPM manifold, especially on a 428. I know others might disagree, but I wouldn't consider putting one on an engine of less than 480 cubic inches. And even then, you're giving away low and midrange torque to a good dual plane. Your gears also aren't right for that manifold. I think you'd be much happier with a nice medium riser 2X4 dual plane intake, if you can find one...
