Re: L78 tune up
Thereabouts...if you get too tight, the thing won't wanna rev and you're putting too much stress on the valvetrain...but conversely, too loose and you'll hammer your lifters to pieces. From .022-.028 is probably the safe zone assuming it's an older stock cam...I've seen a newer replacement cam with 16/16 figure, and then of course some of the newer tight lash cams take that a step further.
