when degreeing in the comp 270 cams, should i be setting my intake centerline at 109 to remove the 4 degree advance ground into them, or should i be setting it at like 105 to remove it? does anyone know. i dont have a cam card since i bought the cams used and i cant seem to find one on the net. anyone got one they can give me the info off of? or let me know what u had to degree urs at to avoid ptv issues.
