Fiberglass hood with Hemi scoop
The reason youre getting a fiberglass hood and scoop is weight consideration ? If it's not entirely weight that's on your mind, buy just the scoop and stick it on your own steel hood.
You don't have to worry about warping panels after they have been out in the sun too long (like just about all fiberglass does). This is what I have done, so when I put my big dollar paint job on the car, I won't have to worry about painting the hood again two years down the road.
If this is your thought too, I bought my scoop from AAR fiberglass and it's awesome.
Good luck.
