Hughes cam?

Yeah i suppose it's relatively tight compared to some of the older profiles, I run .012" & .014" on my hemi 6 and considered that a tight lash. But I've never seen a lash spec as tight as they suggest for those Hughes cams ( .004" & .006" )
I've tried both tight and loose lashes with the Oregon grind I have in Vixen now. Running it at .020/.020 rather than .008 and .012 really woke it up. I had it at .020/.020 initially but I had some detonation issues so I tried tight lashing it among other things. I finally got rid of the detonation problem and put the lash back to .020/.020 and it made a huge difference in power. I'm sure it's all combo dependent.
