I just built an E85 carb and converted my fuel system and everything over to run this stuff and am wondering if I should change my plugs to something more E85 friendly, if they exist? My build is a stock compression 5.9 with 2.02 EQ heads, HEI ready to run distributor, RPM Air Gap and a 750DP converted to E85. I don't recall which plugs I put in it last but I did gap them a little wider for HEI (0.040-0.045 as I recall). This is a street/strip car that gets driven to the track about 30 miles once a week for a little TNT. Thanks!
