Running a MSD 6AL and curious as to what plug gap works best for you guys with a similar setup on a sbc with mild cam. Currently using NGK V-Power non-resistor plugs.

I'm no expert, but I'm sure the experts will need more info on your build...different heads often require different plugs.

Bought this car done and not a clue as to what heads were used. They are late model for sure but not vortec (what a shame). Heck, I still don't know what the cam is exactly or the compression ratio.

The car does run very strong but have had trouble locating the original engine builder for details since buying it out of state.

Thirty five to forty is plenty of gap.

i know mine is 45...

I'll give that a try and see how she runs.
Thanks to all-
Tom
