If you run the MP-recommended .028" lash, it's going to act smaller than a similar duration solid designed to run .018-.020" lash, though.

Keith this is what i measured mine at. theres also an older post on here where a member explains why it comes up that way instead of as advertised

I never measured it myself, but took that info as gospel. I need to go correct that. I have however measured the .484/241, 509/248 and the .590/271 I think from now on I will only post what I actually measured.

I like the lunati voodoo series personally but a full custom cam speced by an experienced engine builder might be best.
