Running MSD Opti, MSD Blaster coil SVO 30lb injectors and Taylor wires. Would u keep stock gap (.050) or something else?

 

I would only use the stock gap with platinum or iridium plugs. With standard plugs, drop it down to 0.035 - 0.040". If you are over 400HP at the flywheel, run one stop colder than stock. All this assumes you are not running a power adder like forced induction or nitrous.

 

FWIW my setup below uses NGK TR6s gapped at .035" (one step colder than stock as Fred mentioned).
