Re: Blue print 347 ford stroker fouls plugs

How can it idle at 600 rpm? My last 347 and current 408 idle at 850 . The 347 had a B cam and the 408 has an X both are in the 224-226 range @.050. "I" found I had to run a hotter plug with an aluminum head. "I" use an Autolite 3924 with 34* total timing. Idles in gear with a "stock" 11"C4 convertor , not a stall convertor. No black plugs
