What, in your opinion, makes a "higher performance engine"? I'm not talking about 7.6:1 emission motors. I'm comparing on blueprinted or better '68-'69 400s with 16 and 62 heads.
I'm basing what I said as a reply to your opinion that there's no performance gains to be had by higher voltage ignitions... The only sense I can make out of that is you must have had low performance engines to have not noticed any gains. To me, the gains are obvious.... And they can easily be documented on a dyno.
