  1.                     Spicer discontinued almost every part if not all for the 83 series auxiliary gear boxes, right along with that 70-8-56 part number.

                        I do have a source and he is looking to see if he might {I say might have one}. If any of you guys run on to any 8341's you might

                        want to snag it if the price is right--just for this reason.

  2. All of that said-what kind of white/gray teflon goo was in the bottom of the oil pan? I would be willing to bet if the intake was removed you

    would find a layer or brick of carbon/sludge under there. I worked auto machine years ago-machined tons of ford blocks and heads of all

    types along with every other engine type. The oils in those days were full of teflon and it separated out real quick especially with short 

    distance driving and aided in a crust forming in areas of low oil flow. I have removed valve covers and intakes from engines that had what

    would be another valve cover underneath that was solid crust same in the lifter galley. The bad thing is {I would bet} the cam and lifters are

    getting tired {probably can't even remove lifters without vise gripes and a case of carb clean}. Now that rear main leak-small block fords

    with manual transmissions/clutch have a tendency to wear the main shaft thrust bearings when oil is really filthy, and a many engines back

    then suffered from that problem. So you will want to check the crank real good, Plus the valve stem umbrella seals are probably cracked

    or broken to bits. 1965 has a good idea.
