So.... it almost sounds like 1). the original points,coil,solid core wires, and non-resistor plugs may provide as good or better performance than a pertronix unit? and 2). original points and coil with resistor wires and plugs would provide poor performance

This will probably open a can of worms...but... what is best "system" (plugs,wires,electronic or points,and coil) for everyday use, driveablity, mileage, etc.

I am running a standard unmodified 261 w/ split exhaust and zenith carb off gmc 270 in a 1950 chevy 1 ton pickup. engine runs fine but have read others online here that say pertronix improved driveavbility and mileage... thought it would be worth the try to upgrade but wanted to get a system that worked well together.... seems like some combinations are a no-no

thanks again for all the help
