Pink cam is the stock one. 3310 should have a 25 shooter in stock form. Go to a 28 to start. As far as being flat above 4500, sounds like the secondries are not coming full open. Here how to check them: With engine off put a paper clip on the secondry rod up apainst the pod. Now go out and give it a test run. Stop and see where the clip is. If they are opening the clip will be pushed down the rod. If not the vacumn pod probably has a leak.
