ignition resistor versus strength of spark

Does an in-line resistor prior to the coil, hurt the strength of the spark as it exits the coil?

I'm trying to put together an ignition set up for a vintage car on a 2 piece points-early distributor.....

I'm not allowed to run a crankfire, and just figured out last night that the pertronix I bought doesn't fit....

what do other vintage (1967S motor) people do?

I have a crane optical in a street car and always wondered if the inline resistor kept me from a stronger spark....

does MSD make a points replacement?

sorry I'm thinking out loud now

If the coil is used in an inductive discharge ignition system versus a CDI, the resistor
will affect the strength (energy) of the spark.

Check out this web site ( www.systemsc.com ) on the Technical page on Ignition Systems
for more info.

so you want to run a simple points and condensor ignition ?
so you're trying to eliminate potential ignition noise ?

Re: Re: ignition resistor versus strength of spark

Sorry I'm slightly confused by your question.
my ultimate goal is to run the best race (non crankfire) ignition that I can for a track only motor....

I want to get away from points for reliability

If you mean ignition noise like the kind that effects stereo's, then no I don't care

thanks again, I'll check out the web site too
