I am restoring my 70 GTO which was originally RAM AIR - I recently got it back from paint shop, have redone interior and am pondering buying the ram air components from repro places (AMES or OPG) and setting it up. The motor is not original, but is a WS code block with 48 heads and Q-Jet carb - #7040263. The previous owner told me the motor set-up came out of a 70 convertable that he pirated for my car. Obviously, it is a manual car.

I have several questions:
1)In general, what is involved in setting up (installing) the ram air and can I even do it with the motor set up I have? I noticed in the restro manuals that there is a foil set up that my block does not have. The hood is original and I even have the original flappers that are pretty much shot and will need to be replaced. And in your opinion, is it even worth it??

2)What does the code GM4 mean on the intake manifold - 400 Pontiac?

3) I have driven it around a little since I got back and I notice the car falls flat when I kick in the back two barrels - Obviously something happened while in the paint shop (for the last year). Any ideas or suggestions on how to fix- I do not want to start fixing things that are not broken- the accelerator pump looks good rubber supple and plunger moves fine, - the back two plates were stuck but I adjusted and now work fine-I was sure that was the problem but it still falls flat when I kick in the back two barrels.

Sure appreciate any help.
