Sparkplug Torgue?

[Swamp Donkey]

Does anyone know the correct torque for plugs on the LT-1--I don't have my manual even close--my foggy brain remembers either 15# or 25# depending upon thread size or something--thanks

I coulda swore it was 22#

My '81 manual says 17-27#. I guess you have a little room to play there.
