all stock valvetrain, yes changed the springs, now if the cam is larger than the base circle is smaller....is it normal for there to be a little "lash: in there, gets taken up when the engine is started again and the lifters pump up that lil extra???

ALSO i lost one of the stock keepers, cant find it any where...any one got just one?? stick in an envelope and mail to me?? lol boy do i feel dumb



Yeah, ide say the base circle should be that different that it couldn't make up the difference, i had my stock cam re-ground from bullet cams, i'm sure they trimed down the base circle a tad.

Maybe Patrick will have what you need, hopefully he sees this & chims in, or you can PM him, i'm sure he will help you out.



if it's a regrind, that's how they get more lift, reduce the base circle, so there is a possibility to need longer pushrods. if you do, these are nice and cheap:

dependng on who's specs you believe, they're .018-.036" longer than stock magnums...

sorry, don't have a spare keeper....maybe try get one from a junkyard, or maybe hotroddave40, or rockauto lists sealed power VK216 for the magnums...
