Performance coil

So I spent 2 hours reading all the post on the Pertronix ignition, which I will install soon. I have a brand new standard Lucas coil, is a performance coil really needed?

Not really. Only if you're looking for the last couple of percentage of performance.

If you bought a standard Pertronix igniter (not the Igniter II), it was designed to work with 1.5 - 3 ohm standard coils. Use your new standard coil and all will be well.

People often swap for a "performance coil" without considering that the other components were not designed to work with the lower impedance. The result can be shortened component life.

Yep, just the standard Pertronix. The quality of condensers and rotors is so iffy , I figured run the pertronix have the other parts as back-up. Plus the Pertronix was only $70 shipped.

Also, there are known quality issues with Lucas 'performance' coils.

The Pertronix will help with the condenser issue (as well as worn distributor shafts) but you will still need a rotor. The premium rotor from Moss, as well as others, is required instead of the standard rotors.

I have 3 rotors that are all the same part# the metal arm is a different length on 1 of them. There is no justice.

Just make sure none of them use a rivet to attach the brass arm to the phenolic body.

If they do!!:
!] Drill out the rivet and fill the void with JB Weld.
'OR
'2] Get a new type rotor sans the rivet.

So is this procedure for all rotors or just with a Pertronix?

Re the rotors: Jeff at Advanced sells the good ones (which he makes) 2 for $15; Moss has them at $7.95 each. At those prices it doesn't make sense to fix the riveted rotors - after all the rotor can be a single-point-of-failure.
