OK, checking the preload without gasket I'm at least .047 too much (gasket is .010) with an .080 lash cap. Do yourselves a favor and get a LS7 valve lash cap GM part number: 12596509 at .060 and save yourselves a whole lot of grinding. No way the lash cap that comes with the cam is gonna work, the only thing it will do is destroy the pump. Even then that LS7 is probably too thick!

So don't change cam lobe and use the cam grinders lash cap cause they are on DRUGS. I did some checking around and the base circle is about .050 to .055 smaller meaning the cap should be MAX of .055 why do vendors just toss in a .080 cap? It makes no sense, and if you call the vendor they will say just run the cap we NEVER have had issues. Right, just go over to the Vette forum and check the guys with cam and lash cap. I can see if this was two years ago and the cam vendors did not know. But now? package an .080 cap that WILL fail the pump? Makes no sense. Off the soap box.
