Does anyone have a link for Comp Cams valvespring specs? I can't find any info from Comps site. I have a couple sets of springs on hand but not sure how they compare with what Comp suggests or if they'd be compatible with the cam I have fo my son's 331 smallblock. Extreme Solid 268, what kind of seat pressure should this cam need to spin to 6500/7000? How much pressure at full lift/over the nose? Bob
