Spark plug gap on 93 Mustang GT?
I have a 93 GT. 5 speed. I recently installed an MSD 6A box in it. I've heard that you can run a bigger gap in the spark plugs with this since it produces more spark. Stock gap calls for .054 so what should I bump it up to. Also, what heat range should I use. I just have your basic mods...GT-40 intake, full exhaust, CAI, e-cam and 24 lb injectors.
Should I stick with the stock heat range or should I change it and what should I gap my plugs at? Thanks.

The gap will get larger as the electrode wears away from sparking and heat.

Check out page 3 of the instructions for the MSD 6A box - they have a section regarding spark plugs that explains how to adjust the gap.
