Here's a very rare thing. A 250 GTO with a cold air tray. It's 250 GTO '64 5573GT. Pic from Ultimate Car Page. Image Unavailable, Please Login 250 GTOs 4399GT and 5575GT have cold air bonnet intakes too. I've seen pictures of 4399GT's engine, but not with the cold air tray. Did it ever, or does it now have the cold air tray? Does anyone have any pictures of 5575GT's engine?
