sorry i have a lot of questions, but i am trying to figure things out and i appreciate the help that everyone is giving me.

spark plug gapping. i have done some searching and have not found a concise answer (if such answer exists). i have read that on a stock 350 it is about .045. i have also read people running .035 to .060. i have also read that to a point the biggest gap you can have without misfiring would make the most power and a too small of a gap could cause me to lose power.

my mods are in my signature. the motor is rebuilt and i dont know the compression ratio, so that might hinder me a little bit, and it also has a lot of mods that i dont know or am unaware of. i have the accell ignition coil and good plug wires and distributer.

what would be the best gap for my situation?

thanks.

.045

youre not going to see any difference in how it runs no matter what but run .045 anyways

have fun

or whatever it says on the tune up label under the hood

I run 0.035 but thats cuz I want to run N20 whenver I want and not worry. If comp ration is high, then you want a smaller gap.

i too don't know my compression. Since I just about never use my N20, I may just gap to 0.05 and see how it runs. I have a very hot spark though. Then when it gets around the time of year that track times may come up, I may close them back up.

You have a hot coil and module? Not too high CR? Try opening up the gap .005" at a time, and run it through it's paces. Get the car up to temp, and load it hard. If there's no misfires, then you're ok, keep going up until it misfires (~.065" maybe). Then go back .010" or so as a safety margin.
Lots of factors affect this, but .045" is a good safe bet. You're not going to gain a lot by opening up the gap anyway...

i think i will start at .045 and see where it takes me. thanks for all of the input.
