I'm looking for REAL information in the form of factory specs or documented statistics on air flow and performance benifits of a Shaker Hood. Thx.

Google is your friend. It's not factory but it's something. Ram air is good for a few ponies, not jaw dropping gains.

I bought a stencil from the original Ford plans for mine and cut the shole myself. Everything is perfect and is exactly as it would have been off the line.. Let me know if you want a copy.

A shaker and ram air both only give you about 5hp and only works at wide open throttle.

But it give you like 1000 style points. They are sweet!

Performance improvements or not, they scream 'badass.'

Correct me if I am wrong, but to run a shaker, you basically need to run a stock intake due to height issues. If you run an aftermarket intake, they are talker and thus throw all the measurements out of whack. I would think the performance improvement of a shaker would not out weight the performance improvement of an aftermarket intake. I always planned to put in a shaker, but I like my Air Gap too much now to mess with it, and I do not have the patience to custom fab a shaker at this point. As for ram air like Chillin posted, I would think this would be worth a little effort due to pulling in cold air. How many of our modular motor buddies spend tons of bucks on performance cold air intakes?

I have a Victor Jr intake and it sits perfectly...

You can go to an air-gap but you need to lower the block in the car with custom motor mounts.

Did you use the fiberglass repo shaker setup? How is the quality?

Waffles

**** no. I paid $2800 for an original shaker and base assembly at a swap meet, I don't trust fiberglass on something that self proclaims itself as an item that will SHAKE.
