Translation: All MSD Products are now made in China or Mexico
MSD, Accel, Mallory, Holley, Quick-Fuel, Barry Grant Demon and about 50 others are all owned by the same group and to my knowledge
they are sending everything they can to China or Mexico for manufacturing... is this the quality you want for your American Muscle car?
Vacuum or Non-Vacuum distributor choice is determined by the engine not your personal preference, any motor that will make 10" of vacuum at Idle with 30* of timing
will greatly benefit from a vacuum style distributor properly set up to run on CONSTANT Manifold Vacuum.
Inductive Ignition systems (ECU) will operate almost any engine efficiently up to 7000 RPM, after that you need a CD (Capacitor Discharge) Ignition system like
the Daytona Sensors CD-1 (3 Rev Limiters) or the CD-Pro (2 Rev Limiters) MADE IN THE USA Ignition boxes.
Coils are designed for either CD type or Inductive Ignition systems and best results will not be obtained from mismatching them, influenced by misleading advertising.
Any ignition system will only generate enough voltage to jump the spark by way of the path of least resistance,
adding a 80,000 Volt coil to a system that will find a ground and jump to it at 20,000V will not improve the flame source
within the combustion chamber.
Optimum results will not be obtained by just adding a quality ECU or modifying the distributor curve everything must be matched
and set up to give your engine the correct timing events based on engine specs and chassis options.
Carefully curving your distributor and then connecting it to an ECU that can't maintain timing (70's style Transistor type ECU's)
or output as load increases and resistance within the combustion chamber increases
will deliver mediocre results at best.
Using an Ignition product designed for a race application on the street will usually result in unreliability and a ride on a tow truck.
If your going to Drive your Mopar then don't use products that can not be easily replaced at a local parts store Reliability, Serviceability and a
properly matched Ignition is a must.
Keep your American Muscle Car American whenever possible beware of absurd claims of HP Increases by ignition company's, no engine will make more
HP just by adding a good Ignition System they can only unleash the power potential of the combination. Make your decision on what ignition to run on facts not opinions, deal with someone who can advise you properly on what your timing events should be and have the equipment, components and knowledge to set it up properly or assist you to do it yourself.
Most Rich Idle, Stumbles, top end power loss, low MPH at the track, poor 60' times and poor fuel economy can almost always be traced back to an inadequate,
poorly matched or incorrect set-up of the ignition system as a whole..... Don't always point your finger at the carburetor it's usually not the issue.
Today's fuel is formulated to run in 2010 or newer lean burn, computer controlled, multi valve, flex fuel, injected, high combustion chamber temp engines and not your classics old school
Muscle Car, we can't change the fuel but we can change the tune-up to burn it more efficiently.
Always Always Always... Ignition First then Carburetion
