    And it will also need a cam button because there is nothing retaing it cam anymore.

    Does that sound right?

    Thanks.

    That and a timing cover that will clear the MK IV timing set. I know the IMCO works well.

    The locater dowels are dead nuts on , two bolts are in perfect position , 4 need to have the holes slightly elongated and the periferal stiffener ridge flattened out a smidge, all bolts are sufficinatly spaced to provide a good seal , Just a quick expireiment for curiositys sake Tom

    Good info, is the 5 cover deeper than the six? What material is it made of? As always you are the man. SJ

    Josh just fabbed this for me on a "6" block replacing a "5" block , the "pinch" was customer budjet The deep "5" stamped steel deal will handle a double roller the, "6" cast unit (w/oring) won't (too shallow) , the "5" uses a gasket (or Right stuff) The Pan arch's are the same uses the same one piece "unigasket" (common to 5&6) Tom

    Thanks Tom. That opens alot of options for this type of deal. The only covers deep enough for a double roller on a six were the CP or Milodon that I Knew of. I have the CP cover on my deal and the polishing made the timing pointer to rounded for my taste. I have been thinking about milling the pointer off and installing an adjustable pointer on it. SJ

    my gen 6 had a mark4 cam in it when i got it. cam button against an imco cover. i changed the cam and it is still a mark 4 deal, but this time a new imco cover using the water pump as a cam buttom. imco covers are very nice. i think b&b is almost identical.
