ZL-1 Spark Plug Gap

[Camaro Rick]

Thanks Sam, I didnt know if there was a "sweet spot" for the gap on the plugs, and if there will be harm in the ignition components eg. amplifier, coil. if the gap is too large. It is hard to time the engine at idle as it is all over the place with the rough idle. I have the curve for the distributor and have been setting the timing at a total of 31 degrees @2000 rpm. Does this sound correct?

For starters, is your timing all in by 2000, because if not you're simply guessing. You need to run it up to 3000 or more and see where your timing is done at, and then you can set your total.
