[QUOTE="dan filipi, post: 19048, member: 54"] Ron, that makes the most sense out of anything why the compression is higher with it's relative index point as compared to the earlier cams. Taking another look at it (after having a nap), running it may not bump a valve because the valves are completely closed [i]earlier[/i] in time than with the other cams. What I mean is, #3 intake is the valve which causes the cam to move off TDC when the belt is removed with the stock cam. With the 1200 cam this valve is already closed at TDC, the cam has to be rotated a good 5 degrees before Top dead center for the rocker to contact the valve and cause that same resistance. This "earlier" valve timing looks true in all the lobes. To prove or disprove this theory I think I need to install this cam in the left side to see if compression increases. If this is true and I've stumbled on some hot rod mod then I'll be looking for another right 1200 cam, after running it with this one first. [/QUOTE]
