    The stock disc/plate can hold for a lot of power.  The biggest drawback
is the material really looses it's grip when it gets hot.  If you slip it,
it won't hold.  Keep slipping it, and it'll glaze and it's done.  But if you
keep the heat off it, it's suprising what it'll hold up to.  I used to drag
race my old 89, the 3.2L with a 70 hp shot of nitrous.  No slip, just drop
it off the line, and bang gears.  Did pretty good.  The PP straps/rivets are
a weak spot though.  Most aftermarket clutch's replace the rivets with
bigger ones, and use wider straps.

and friction disc?

    I recently tried a different version (9.75" 9 puck disc vs my current
9.25" 9 puck) of my current clutch on an 8 lb SS flywheel, and ran into
slipping problems bad.  Still haven't fully sorted out the issue yet, but I
tend to think that the bolt hole filled surface of the steel insert on the
flywheel reduces friction area/holding power.  I'll know for sure when I
test my current clutch (PP and disc - known good on a stock flywheel) on the
same flywheel.
