Coil mounting

I've had the same msd blaster 2 for 9yrs.
I had it on my slant mounted on it's side to the fender.
That same coil was then on my 340 [stock location] and now on my 410 [stock location]

No problems.

Even mounted upright, the g forces would move any air pocket [if there was one] exposing the windings at the most crucial time=wot.
