What spark plugs and what gap should I run
I have 91 Coupe with a 327 stroker with edelbrock performer heads and vortec supercharger (the small boost one 5-6psi)
I know edelbrock recommends champion RC12YC but is that good for my combo or should I run somthing else and what gap any suggestions are greatly appriciated thanks.

I just run old copper autolites 2 heat ranges colder then what they recommend as far as gap I would start at .030 if you get spark blow out then close them up some if you don't then you could go wider. I only run about .025 but I also run much higher boost. You may even get buy with only one step colder with the low boost numbers. If you have a MSD and a hotter coil you may also get by with a wider gap it is all T&E.

Yea I was wanting to swap to autolite 3923 or 3924 just wondering which was best I will prob go one step colder and see how they do.
I have (MSD) street fire box and coil so not sure on gap I will try .30 or .35 and see.
Thanks for the info.

Thanks for the input the car has Champion RC9YC plugs in it now I noticed it is same heat range as 3923's but now another question the champions are non resistor but I drive on the street in traffic mostly so resistor type or non-resistor type?
Sorry just got this car in febuary and never had F/I car so just trying to learn a few things.
