Curious about HP possibilities

But it is well known, that the 3B distributor is very narrow and the old WR 
on the picture don't have
knock-retarding, which also require some degrees of freedom.
The sparks just take the way it can and under high compression load it may 
fail to find the correct cyl.

Above 400 Hp I would choose an AAN valvecover or similar with full 
electronically management.

I remember my own 3B with 369 Hp. Small ripples at the power curve at the 
dyno were assumed to due to the
ignitionsystem were close to the limit
