    1964 Chevorolet Impala SS
    327ci (Rebuilt) 25K Miles
    350 Auto Tran

    AfterMarket Upgrade(s):
    Edelbrock exhaust manifold, 300 cfm 4bbl carb, electric fan, digital dash, 95amp alternator.

    I need to upgrade my antiquated Mallory Unilite Electronic Ignition (15 years old) and
    signs of failure!

    What are a few recommended HEI distributor(s) that would fit my application.
    This is a cruiser/custom, no burning rubber!

  3. Keep your antiquated Mallory for nostalgia and put a PerTronix Ignitor inside it :)

    Anyone have any experience with these? Seems like a deal with new cap & parts instead of rebuilding an old one (the points one Squirrel posted,For some reason this post didn't show his quote)

    Mallory is out of business. If you have a failure, it's over.

    I had a hell of a time getting parts for a Mallory 40 something years ago and I worked for a guy who set them up for the local racers then. Every time we needed anything for them we had to make a special trip across town to the one parts house/speed shop that stocked the parts.
     
  8. Stock HEI unit from your local wrecking yard.

    make sure it's not worn out. A lot of them were worn out when they were only 5 to 10 years old.

    also make sure it does not have the 4 wire computer plug.

    I would put the point dist in it.
    You will have to maintain it but that will keep you in touch with your car.

  12. Speedway sells one for 69.99. I've had one for 2 years and still runs fine.

    Use a GM HEI just check for excess play in the shaft [ this the only part that mechanically wears out ]
    Install a new MSD module [now available with a built in RPM limiter] and a new Cap with a Good coil and it'll be better than most of the Cheap "High Performance" HEI's from China.

    Here's the part to use

    I used a MSD module for 20 years in my Road Racing BBC with a GM HEI, it has never missed a beat [I have turned it to 8k on a few occasions]

    The mechanical advance mechanism also wears out.

    The complete rebuilt is less money than buying a used one from the wrecking yard and replacing cap and rotor and module if needed in most cases for a general street driven rig.
