Ignition problems
My 1966 327/350 starts good, but when winding out in the gears the it misses badly even though it acts like it wants to run great. Would a Pertronix ignitor or a MSD system help the intermittent firing problems? Thank you for your help.

I agree with John.
The stock ignition is well capable of 6500+ RPM if everything is in good condition.
Instead of throwing dollars at your high RPM miss, find out what the real problem is.

When was the last time, date and milage, you did a full tune up with all new ignition parts? Things deteriorate just from age. Start fresh instead of replacing one part within some of the other questionable ones. Plug wires come to mind. Just a thought.

I am very happy with my 2 ac delco rebuilt and recurved points distributors. Have a 65 cast iron Chevelle unit in my carbed 84 C4 and a 70 Pontiac aluminum one in my 65 470" Gto . Using Smp Blue Streak cap, points and condenser. Had advanceddistributors.com in Shakopee, Mn do the rebuilds for me. I have been stranded with hei coil and module failures more times than I care to remember!

Colder plugs will foul quickly in street driving.
Use Delco D106P or D106PS points (Ebay/cheap)...........or a set of Delco D112P if you can find and afford them. One set should last 12,000 to 20,000 miles.
. Probably a lifetime for most of us.What is the condition of your wires?? They need some love also.

Yeah. Over the years I have had them all. Mallory, MSD, Mopar electronic, GM capacitor discharge, Pertronix etc. Unless you have a TRUE race car that you are running 8k rpms or more the factory single point distributor is my choice.

These systems have very few, if any, moving parts. If the fuel is clean and they are set up properly, there should never be a problem.

As has been suggested, before condemning the points system, try to find the root cause. A properly adjusted and functioning points ignition will return many miles of smiles.
