a dial back timing light is something like this:

basically you can get it to total timing, for example 36 degrees, and then you just line up the zero mark on the balancer with 0 on the timing tab.

Update: car runs better, cooler, and faster.

Mr Gasket is my hero lol. Black/silver spring= full mech @ 3,000 total 40°, with vacuum capped. Added vacuum, adjust idle and seems to run cooler, definitely better below 1,500. Is it faster, no idea, it spins tires through 2nd no matter how bad I tune it.

BTW, anyone else hate the distributor “cage”?

Congratulations! 40 degrees is high but glad to hear she is stronger than ever.

i agree 40 is on the high side. I've run 38 on a bbc but 36 is much safer to avoid detonation.

Yup, leave it off and save yourself some angst (and, possible cut wires in the future).

I would have set lower, but that metal housing stops me from turning it more clockwise (It was 85 yesterday and the car never went over 210, in a mix H/C driving). All I need is another 1" lol. Now the chrome go faster cage does screw "numbers matching" Pretty sure I read that on Google.

If so inclined you can probably fix the interference problem with the cover by pulling the distributor, knocking out the drift pin in the bottom drive gear, rotate the gear 1/2 turn and reinsert the drift pin. The gear has an odd number of teeth (13) so doing this moves the distributor 1/2 tooth in relation to the timing or about 12-1/2 degrees. Usually with today’s questionable gas around 35-36 degree is safe for the engine.

How much, in degrees, should a distributor more with the chrome cage still in place? Im asking to see if I just rotate the plug wires one space.

Would I more the plug wires clockwise or counter clockwise?

You can move the plug wire one terminal. You would need to move them clockwise to move your vacuum canister counter-clock wise.
