The little Blaster SS coil worked so well with the E-curve distributor that I designed a bracket for it. Part number AR307. It is a fairly popular product these days.
MSD told me at their SEMA booth they changed some things internally with their E-curves and they were not interacting with the SS Coils whereas earlier in production there was not a problem. It's just my experience from three years ago.
I simply switched my SS Coil for a Blaster II and fired up and ran smoothly. Put the SS Coil back on, and it struggled to fire and run. Again, that was three years ago. Hopefully they have updated things to work again with the SS Coils. I'd want to hear from MSD what the current situation is. Or from others that have run SS Coils bought in the last 3 years.
My E-curve with the Blaster II has worked flawless in the last 3 years and 8,000 miles.
