autolite 25's(plugs)
Amsoil, Mobil 1, Redline, or Royal Purple(tranny fluid)5.6 pints.
Motorcraft 75W-140synth and 4oz of FRPP friction modifier.(diff. oil) 3.75 pints.
peak or prestone mixed 70% water and 30% antifreeze.(1 gallon).
In stock form, the spec'd differential oil is in the neightborhood of 89W-90. In later 8.8's, the fluid-viscosity he mentioned was indeed used, but AFAIK, the lesser-weight stuff is still in vogue with the fox III guys. That said, ahem, I do run the thicker oil. BUT I probably would not in a colder climate (I live in the desert).
And I still recommend 50/50 water/antifreeze mixes, especially since it's coming up on winter and we don't know that you dont live in Alaska.
How many miles does the tranmission have on it? A lot of tranny techs don't recommend changing the transmission fluid if it has not be maintained on a regular basis.
