Need help with rebuild

,it's not the same spec if cam is perf. replacement(i.e."purpleshaft")the spec. is way looser.

Good info on all that, especially the MSD guys advice. I'd trust most salesmen 'bout as far as you can throw 'em. I quoted the info above, cause to be more 'universal' I guess it should be worded 'lash the cam to whatever the manufacture suggests'. My OCG 819 lashes at .010 and .012, at stock specs it runs horrible. Carry on.:burnout:
