Default spark plugs

I am curious to find out what is the best spark plug to run in a n/a 563 cubic inch big block Chevy that runs on methanol. The motor has dart pro 2 heads and has around 14-1 compression. I am running a 1050 dominator. I am just curious what everyone is running for spark plugs and why. What is the best way to determine the correct plug. I would like to try the e3 plugs but have no clue which one to run. Any suggestions will help. Thanks

E3 is not for racing in my opinion, just street cars and maybe just a fad?

NGK plugs work well and can be read because of their plating that changes color with heat.

R-5671A-8 or 9 will work in alot of instances. I like 8 for gas and 9 for alky. Every engine combination is different though.

In my opinion, you won't find any magic in trick-of-the-week spark plugs. They're just gimmics designed to sell spark plugs. Stick with what you know works.....again, just my opinion.

i second that :wink: NGK's are the only plugs to run.... i actually tried the accell U-grove plugs before and they worked very well.... very short and great for headers......just hard to find .... NGK's are everywhere
