Spark Plug Gaps

[coralcoupe1993]

What plug and gap would you run on a 5.0 with H/C/I?

.040" or so should be fine if you have a good ignition & coil.
There is no benefit H.P. wise to running a bigger or smaller gap, you just need the gap set so that you get a clean spark. Try .040 and see if it works, if not try .035 or .045, just keep trying and see what works for your particular application. N/A shouldnt matter as much as a blown application, so it shouldnt be to tough to get it.

Thanks. The big block cars dont seem to care what you gap them at - this coupe gets kind of pissy when stuff isnt dead nuts.

your not supposed to change more than .008 and you should change it in .002 increments
