Now, the bad news. The hood Ram Air pan fit perfectly, foam seal and all. Cutting the hood brace took only a few minutes.
Upon attempting to close the hood, however, I discovered that there NO CLEARANCE between the front of the carb pan and the hood pan. They touch at the very front of the carb pan with the hood closed. The rear of the carb pan clears by about 1", which is just about right to compress the foam and make a seal.
Now, I need to figure out how to lower the front of the carb pan by about 1" so there is room for the foam to seal, but no contact between the two pans. I can see that about 3/8" could be removed from the plastic carb pan at the front carb air horn location and about 3/16" off the carb pan at the center carb air horn location. This would give more than 3/8" of clearance at the front of the pan due to the geometery, but I don't know if that would be enough. I'm going to try it. If not successful, I'll cut the top off the carb pan and cut a wedge-shaped section out of it to lower the top of the pan. It will take adhesive and body work to make it look nice, but the end result will be worth the effort.
If any of you have ideas or know of a carb pan that is lower than the one I have, please let me know. Mine is as a plastic carb pan and I suspect they are all the same. When I set it on a table, there is 3 5/8" from the top of the pan to the bottom of the front air horn connection.
