Hopefully moderator will let this this reply through because, even though we'd agree'd to disagree, you posted yet another message on the topic. I then humbly suggest that until some startling new info emerges we move on to other topics. To answer your question first: yes, bridging DeLo resistors WILL increase spark voltage. In fact DMC factory design starting relay does that every time you turn the key. (That's what the relay next to them is for). Now my question: Why does my simple $30 ignition coil continue to bother you so? Are many *OTHER* DeLo owners reporting improved performance from higher voltage coils. Why don't you ever flame them? MSD, Pertronix, Mallory, Jacobs, and even Accel have built quite an industry out of nothing but "nice high numbers on boxes" BTW. Could point you towards just as many websites (vs books) that say I'm right and you're wrong, but what would that accomplish -- we'd end up right back here in original disagreement. Let's agree one more time to disagree, then not waste any more bandwidth.
