John:

** I doubt that the stronger spark causes a power loss.**

It *could*, depending on the timing.  A stronger spark has the effect 
of advancing the timing. That could increase or decrease power based on 
the thetaPP at the normal timing and power setting.  If the power is 
reduced, the stress on the engine will go UP with the movement of 
thetaPP toward TDC.

I constantly remind myself that when I was dinking around with the 
timing on my 57 Chevy back in High School, I'd never heard of internal 
cylinder pressure or thetaPP and I was doing so on a water-cooled 
engine with an IRON block and heads.  That's probably why I didn't 
destroy it.
