I had AJ Castilini(SP?) do mine, it is real sensitive on the dyno to jetting, one jet size either way would make it lose power BTW, E85 and bracket racing are made foe each other, hardly any change in ET from early morning to late afternoon Don't tell anyone else that though AKA I would worry about te main webbing on any stock 440 block if you decide to RPM it much above 7000 RPM on the edge on the tune up Run it slightly fat and don't push the total timing and you should be okay Mr.Cab Racing and winning with Mopars since 1964.
