thanks for replies. I believe the little sube is a perfect candidate. The accel coil at 33%(? something in that realm of number games- I went from a rusty dud 7000volts to 11000) stronger was quite noticable, and I too had to back off the fuel..now at all heavier throttling it is at the gas mileage it was before just to drive around easy.
I finally managed to make exhaust and other things surrounding a higher coil strong enough to take it to another level...including the unibody...with a secret located aluminumized electrical dispersing metal.
The winter still takes awhile for heat on my 9:1 engine, but did get helped with bigger coil. I may try out the msd combo, thanks.
The 9.5:1 sube 1781cc (same engine really but pistons) would not like this I am certain, the 9:1 is like having a long stroke little engine because of the bigger chamber to fill and squish less.
