Dual sync plug gap

[387lx]

Just trying to find the recommended plug gap or at least a good starting point, for my 387w running on a terminator x with a Holley dual sync distributor?

If boosted I would be in the .022 to .025 range.
If N/A I would be in the .035 to .040 range.

It’s turbo’d going to be low boost for now until I get a meth injection system. Was just curious because was reading online that the electronic ignition stuff likes wider gaps ao was just looking for people’s opinions

If you have a strong ignition system/coil you may get away with more gap at the plugs. You can experiment a little and find out what the limits are. If you get a misfire under boost, then tighten up the gap a bit and try again.
