Thread: Shaker Hood Grating?

Tweet

I have been informed that I was not using the right terminology; I do not want to build a "shaker hood" per se. I thought that a "shaker hood" referred to a hole in the hood through which the engine was free to rattle back and forth. Have mercy on me; I'm new at this.

What I have is a hole in my hood that's roughly triangular, 15" on a side, with a black fiberglass hood scoop over it. (I did not do this; the car was previously owned by a madman.)

The engine I'm building will project through the hood about 10", and will have a Hilborn-style scoop 20" long and 9" wide. What I want to do is open up the hole in the hood to the dimensions of the scoop. This will make it about 6" wider than the scoop on each side. Probably a bit more, as the current hole is off- centered on the hood by about 1/2".

I was thinking to use some grating-type material -- expanded metal -- either tack-welded or riveted to the underside of the hood, to close the gap a few inches on each side. I still don't know the exact term for this. Besides, of course, "lunacy," "sacrilege," or "rat rod."
