Hi All, My 455 has developed an annoying miss under part throttle. I am running a GS club SP-2 cam and a 4 speed. Checked the timing, it is at 14 deg initial and advancing properly, I have since replaced the points with a Crane module. Compression is 190 lbs in all cylinders. The engine seems to idle o.k. and stills pulls fine at WOT. :3gears: The carb is fairly new, no apparent vacuum leaks. Any ides on what I should check next? Thanks , Adam
