Timing will not change by changing cam. If you turned the crankshaft you will have to bring back to T.D.C. You could possibly have the distributor installed one tooth off, or if it is 180 degrees off just pick it up and rotate back to your mark. You can usually just rotate the cap if a tooth off to make sure it is firing #1 cylinder at T.D.C. Just set the final timing with light after you start.
