I have restored them go by the curve, actually do not remember where the initial timing is I can look it up though. I need engine, year, carb and trans.
Here is a bit more information:
1965
273 2 Barrel with the Stromberg Carb
727 Trans.
Looking back at what records I have (which go into the mid 90’s) the cap and rotor were replaced about 10 years ago (but only 300 miles ago). I am not sure what exactly they put on as the PN isn’t clear. So I am not sure what the curve is in it exactly as you need very long arms on a ‘65 to reach across the engine to the throttle as you stand on the passenger side with a timing light. I also live at 3000-4000 ft of elevation and I run 88 octane as that is the ethanol free I can get.
Also, I think this was talked about in an earlier thread a few years back but again not sure this applies to me anymore. Timing a 273
