What is better - dual point distributor or electronic ignition?

Motorheads back in the late 60's/early 70's were into putting name brand (two come to mind) dual point ignition systems, with high ouput coils, on their street rods/muscle cars. I guess the overlap of the dual points would cause a more powerful spark. Heck, I put a set-up on mine. Did I think it really lived up to the billing? Not sure, since a person's mind can be greatly influenced by expectation, aftermarket ad claims, what other's say(did THEY really know fro sure?), etc..

If electronic spark is dictated by a single dwell angle, then you would think the dual point would be better. But -?????

Any knowledgable opinions on this?

not an expert but...

I've had a couple of V-8s with dual point ignition and they were bad to the bone..... but I doubt the dual points was the only contributing factor I'm more comfortable with points but I'm slowly learning electronic ignition and you really can't beat their reliability! I'm pretty sure all the NASCAR engines use electronic ignition, it be hard to find a street car with that much power

Duel point was to get away from point float at high RPM
Electronic does not float so the "float" problem vanished.

dual points

The sales pitch on dual points was they added dwell time therefore allowing a longer time for saturation of the primary winding of the coil. Just some history, Ive seen it proven that a stock delco coil would put out as much voltage as a mallory.Electronic is much better in every way.

A motorhead friend of mine had Mallory. I had Accel. I guess after reading your replies, and the consensus abourt this, that I should look up these makers to see what they have to say now about them products, and if they even still make them or not.

Electronic distributor with an MSD ignition unit is the way to go.... PERIOD!
