what plugs should I use on the juice?
I have a 91 305 stock block, I am running a 100HP shot, I run 93 octane on the juice, 87 octane daily, What spark plug would give me the best results for both daily driving and racing? I have used the stock# plugs and seems that it is starting to run a little rough now. Thanks in advance
