Could it be the air pump or is it more likely to be something else 1985 Corvette runs rough when it is cold and check engine light comes on?

You need to find out the code that is bringing in the check engine light. To do this- under the dash on the drivers side to the right is a computer connector. Turning the key on and shorting out the top right connectors will cause the cooling fan to start and the check engine light to flash. It will read a code 12 3 times( count the flashes with a small delay beween each flash followed by a long delay) followed by the fault repeated 3 times. Your question is too vague to have a good response to. Any number of things could bring in an alarm- O2 low, MAF,EGR operating,TPS low or high voltage,etc. I suggest you find the code and ask another question. You might find the answer is in the code.

What would it take to fit a late model camaro engine into an older corvette?
Depends on how old. Would help to know what year of Camaro Corvette we're talking about, and also what transmission both vehicles have. It could be as simple as reflashing the ECM, or could be more complex, involving new engine mounts, fabricating brackets for components which aren't positioned ideally for a Corvette engine compartment, maybe even a new transmission, if you're swapping in something like a 6.0 in a car which used to have a 5.7.
