While it is a cool idea, going through all the trouble for the ram air won't really gain much if anything. If you want a good cold air setup, get the I6/460 tube from the air box to the radiator support. Its much better than the 5.0/5.8 one.
A hole on top of the manifold is fine!!!!!! If you have a carb sittin on it.....ha ha.....now that will work with ram air.
I'm sure you could make something work, but the amount of time spent versus power gained is minimal. Since you have access to the parts in a junkyard, there are some other ways to get the 302 up and moving....
- Get a used washer fluid tank, wire it to a switch in the cab and hook it up to the intake tubes. Fill the tank with dehydrated water and then inject as needed whenever you need a power boost.
- Swap in the spark plugs from a non-turbo 6.2L Chevrolet diesel, preferably around a 1985 K3500 4wd model, altho the C2500 2wd models will work if thats all thats available
- Lastly, see if you can find an early 1970's VW Bug, the radiator hoses off those flow much better than the stock ones that ford puts on the 302's going to the radiator, with the added power of the diesel plugs and dehydrated water, you will need the added cooling capability that the hi flow Bug radiator hoses provide.
I found the best way to get more power out of my 5.0L was to get a round tuit and a pair of adjustable power bands controlled by a Kuhneutson valve.
