bouncing timing mark

well looks like the idle quality was tossed out the window with the choice of the 509 cam there is a alot of RPM fluctuating going on at idle due to lope. the dist, oil pump drive and bushing and timing chain all get jerked around when at idle with a large cam. i believe that at idle as long as it is not stalling the real test is at or around 2500 to 3500 RPM if it smoother there. good, if not then there is something wrong.
Peace
