From time to time someone inquires about trimming the hood on a 68 GTO for the ram air pan so I thought I'd post some photos showing how I did it on my car. I decided to replace my original hood so the new one would need to be cut for the ram air stuff.
I figured the best way to trim the hood is to make a template. A portion of the hood pan is stamped and a portion of that interferes with some of the hood bracing so that needs to be cut out.
- Cover the engine side of the pan with pattern paper
- trim the edges and trim away the center round area
- feel for the edge of the stamping and trim away that portion
- position the pan on the hood
- center the air cleaner opening...not the pan. Note the alignment hole at the front.
