    "Is there any way to 'fake it' and run points or a breakerless SE with the appearance of TI?"

    The Breakerless SE isn't going to fool a good judge into thinking the ignition system is factory original TI.... The original TI distributor has a magnetic pickup with two wires exiting the distributor to connect to the TI amplifier. The Breakerless SE system uses a single wire from the coil to power the solid state ignition module that installs below the distributor cap and it CAN be seen by simply lifting the point adjust window on the distributor cap...

      I wouldnt want to fake it. That just wouldnt be worth all the work put into the rest of the car. After Judging, down the road a while if it starts to act up would I change it out to breakerless??? Yes I would. But I have heard from other members that there T.I. works fine. Are these systems really that much trouble?? I really dont know I have to rely on other owners. If they are problematic, what can you do to correct it. Surely they werent all bad. I would appreciate any opinions and information.

      Thanks Ned

        Ned,

        The worst parts of any of these Delco systems was the amplifier, amplifier ground and the stationary pole piece in the distributor.
        The original Delco circuit boards were a bit of a problem but that problem seems to have been eliminated with the newly available circuit boards from M&H in Californai. (I bought my M&H board from T I Specialty)
        The 2nd most common cause of failure is the small strands of wire as they enter the stationary pole piece in the distributor. The problem is, the unit almost constantly moves/rotates in the distributor as the vacuum advance unit moves the assembly when the vacuum signal changes. This moving is almost continuous and the results are a broken lead where the small wires enter the unit.
        I won't have that problem on my 66 L72 car because I plugged the vacuum hose with a small steel ball 25 years ago.

        In the twenty five years that I've owned and driven that car, I've replaced the amp twice. Once in about 1985 and again about two years ago.
        The problem both times was caused by moisture in the amp. One lead to that little remote gizmo in the housing corroded and broke. I could have soldered it but decided to go with the new "all in one" module from M&H which elininates that diode and the problem.

        I've driven that car all over this country and wouldn't hesitate to do it again, as long as the vacuum advance is plugged and the amp box has a good ground.

          i already posted my opinion for what it is worth. the amp was the main problem and with the after market internals it sould be fine.

            Is the breakerless system in any way comparable to the TI set up. I would think the switching from the magnetic pluse distributor to the amplifer and then from amplifer to coil is much better. The switching is independent from each other correct, kind of like a relay?? The breakerless is not like this but it seems much better than points.

            A friend of mine took a TI off a car the owner complaned about intermittent operation. I am confident the problem is ground related, the complete system ended up in my basement.
