1969 distributor rotor recommendations?

[Paul S.]

I have the distributor off my '69 base model (300 HP, 350 CID), and since I have no idea how old the distributor rotor and points are (they look pretty rough), I am going to replace them.

I read some old threads on here regarding rotors, and I am thoroughly confused. Standard tip... extended tip... I am not sure which to get.

Was the original a Delco D-409? If so, should I try to find a NOS one? Or would a D-409R be better? Or something else entirely?

I have a stock Delco "Patent Pending R" distributor cap.
Any help or recommendations for a good rotor would be greatly appreciated!

Thanks,
Paul

Re: 1969 distributor rotor recommendations?

Any "name brand" rotor you buy, including "Delco" is likely manufactured by Standard Motor Products, and this applies to nearly ALL ignition system components, so just buy on price and convenience. Since the rotor cannot be seen during judging, you just need a functional replacement.

These rotors are likely of the "short tip" variety that was apparently for the purpose of EMI reduction along with resistor type plugs, and both went into production in 1969.

I recall that there have been reports that a "long tip" rotor is available in the Accel brand, but it is likely more expensive than the SMP-manufactured part that is available in the Delco, Standard, Niehoff, Echlin, and other traditional replacement brands. Avoid any "off brand" or "economy" parts as they may not be manufactured to OEM standards like the SMP ignition parts.
