Could be okay, I've got some really old timing lights here that go with my Sun diagnostic machine and I know that's from the late 50's early 60's. Even that one has dial back adjustability. Still works fine but I prefer to use a more modern timing light with a dial back that is probably 15 years old and works on every ignition system, been great for me. I have a newer digital timing light but I've found it works a little funky when you mess around with high energy systems like MSD Digitial 6 and 7 boxes,,,so I always tend to fall back on my trusty 15 year old analog piece

You don't need the dial back as mentioned, I also mentioned you could get away with timing tape for about $10 and accomplish the same thing,,,providing your balancer hasn't slipped that is....

You really should verify top dead center on the balancer and remark it if necessary before you install timing tape, otherwise the tape will be off too since you will use the "zero" mark to line the tape up.

I'll get you a couple of HEI pics,,,,hang on.
