wt spark plugs do you use with msd or crane box??? and wtdo you gap the plugs ???? some say 60 ?i have mine at 40

Normal, meaning non-platinum or other 'exotics'.

Plug gap of .040"-.045" is plenty. You'll get many responses of people using anywhere between .035"-.045." It's all good.

according to msd and crane do not run platinum or other exoctic plugs, will burn the tiny tips off from what they told me and .035 is what they told me...Rob

wt kind of plug do you use on your motor???
