I am interested in people's opinions about spark plugs for an 427 FE with Weber IDA carbs. I read in the Shelby American magazine that the 427 was recommended to use the BF #32 plugs. I was wondering if that were still the case today and with using Webers. Somewhere I was recommended to use #42 plugs but these may be too hot a plug based upon the recommendation. What say ye, mighty forum readers??
