blaster coils?

[SCHWARTZ]

would one of those msd blaster coils work with the volvo ign system? theres two in the links but i dont know which one would work better.. would these make an improvement as the spark seems weak to me and if some extra power could be had for £50 thought it would be worth a shot:scratch:

define weak. you want a nice fat tip on the core of the spark plugs, not a needle type, if the sparks being blown out then reduce the gap, think mine ran at .8. std coil pack worked fine on mine to 25psi.

Cheers haz, I spoke to scoff and he reckoned they are a waste of money for what I want so im going to stick with the standard one.
