How tight can I go before damage occurs? Am I stuck with this lash and need to either let it be or buy a newer design camshaft? I would like to try the small lunati voodoo solid to b honest. Thanks for your time

If it seems to be better with tighter then you need a bigger cam Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)

Quote: Normally .010 tighter (maybe a tiny bit more) is okay on the loose lash cams like the Mopar and Isky with .028 lash. If it seems to be better with tighter then you need a bigger cam I pushed the 590 grind even further, setting the lash down to .014 cold with iron heads. My big stroker liked it. The ramps will be more gentle when you tighten the lash, so the duration goes up, but the first part of the actual lift is a bit lazy. The danger point is not letting the valve seat properly, which with .014 hot shouldn't be an issue at all. 8..603 156 mph best, 2905 lbs 549, indy 572-13, alky
