Gas Overload

I have a SBC 350 with a 750 edelbrock and it seems to over load the spark plugs and cause it to mis - can I use a different plug with a higher spark or?

Huh? Do you have any clue what it is you're talking about or what you're asking? A plug with a higher spark? WTF???

I think he means a spark plug with a higher intensity spark.....you can try Bosch Platinum +4

If something is snuffing the flame, you should really address the cause. If you are overfueling and like it that way then you need to consider the heat range of the plug. Of course bore wash, etc are just side issues.

Newsflash Twinkie. A Bosch Platinum +4 plug DOES NOT have a higher intensity spark that a normal sparkplug.

umm really you can't get a 'higher intensity" spark plug. Even if you get a very high powered coil, it only uses what it needs for the spark to get across the gap. So whether the coil is way overrated or just right it gives the exact same spark.

Is that right? So if I have a potential of 40kV between two electrodes and another with 20kV the arc will not be any different?

I would recommend trying to adjust your floats, but I'm sure you have no clue what that is. You can also try using a set of plugs with a higher heat range...but that is more or less a band-aid for poor carb sizing/tuning.

So the box says "delivering the most powerful spark" for no reason at all?

The containers of most fuel addatives usually say something like "guarenteed hp increase"....and most of the time it's BS. Yes the spark plugs have hotter/cooler intensities....but not too sure about "the most powerfull spark"...

No, there IS a reason. It's called advertising. It's called convincing know nothings that they actually know something. New, improved, better than before. Ever heard those phrases? If you want to argue the point, explain to us why and/or how they "deliver the most powerful spark". Remember, science not slogans.

The thinking behind the Bosch-2 and +4 spark plugs is that moving the ground electrodes out will unshroud the spark...racers have been indexing plugs for years to try and gain that extra few hp by unshrouding the spark...but on a typical street/strip application it would most likely be worth nothing.

Don't flame for asking a stupid question, but wouldn't that mean that since the higher intensity spark plugs make a bigger/stronger spark, they'd need more electricity, which would lower horsepower?

I thought the four prongs just means there are four alternative paths to ionise the air and jump a spark.
