i run 10.75:1 in a 357 with dart 200 heads. I dont know if you are familiar with AC Delcos heat ranges, but i run an equivilent to the r 43 ts. I dont have any problems. the more compression the colder the plug you should run. Also, the E3 diamond fires are a very good plug, i would recomend running those, they made a difference for me.

i run the 215 pro 1 plat's w/supermod port job on a 350 + .060 with 10.5:1 compression on the street with 2 different plugs...best plugs i have ran so far is the AR3935 by autolite great cold plug and i don't have any problems with it fouling out on 93 octain another good plug that i run is an NGK R5671a-7 I also run a complete MSD ignition and 6AL box. both of the plugs were recommended to me here at the forum. both plugs run great IMO i'm sure others will comment on the plugs...seams like this question pops up every other week or so....LOL

hope this helps

the R5671A-7's or -8's will work fine. Out here we get what we can. Parts stores don't carry them in stock half the time.

AR3935 Autolite and don't pry on anything, they will work well.
