| RE: 427 valve spring specifications? |

| It depends on what grind you have, but typically 125-140 seat and 325-340 open. To help see what kind of wear pattern it will have you can put toothpaste on it and light springs (such as rocker shaft springs) and rotate the cam and look at the pattern. The back side of the lobe must have the pattern off to one side as well as the lifter must have a "ring" 2/3-3/4 of the way to the outer edge. Its a lot of work, but so is the heartbreak of a wiped out lobe. Hope this helps |
