Still cast in USA, but I cant confirm state as CA has 3 Edel foundries. Only one does this older sand cast stuff. their new stuff is permanent mold when it can be used. I wrote this back in Aug of '20. I had the 2 on the same bench at one time, still looking for the pics but the difference was obvious. Edel isn't any better and this was before he passed....
"..And I've held both Air-gap and Crosswind intakes at the same time and compared the fit and finish. The Crosswind was hands down the winner. Laser straight port walls, no core shift. Holes were cleanly tapped. I had to polished knockoff version so I can't comment on the texture, but I could tell the plenum volume was less on the crosswind, slightly shorter. The complaint I hear on the crosswind is that the flange angle has been machined at the wrong angle(!). Now that's a pretty hefty mistake (maybe be a one off that got through and the internet jumped on it like the glued together prototype turbo housing that got sold) and can be mistaken by poor head milling but since I never installed the crosswind, I cant comment on that but I did lay it down on an LA and there were no gaps. The Crosswind does not use all sand cast cores as Edelbrock does, they use steel molds at the flanges so there is no core shift.."
