Looking back at this ancient thread, I have an 85 D-150 that came from the factory with a slant and a 727. The 727 which everyone else I talk to wants me to throw out in place of a 904 I ain't so sure I'm sold on that idea..... Me +904s don't seem to get along so well. I definitely like "different".
And I even have a good rebuild able 904 core sitting here now.... But not so sure I want to demote my truck like that.
I ain't sure the slant EVER needed a 727. I don't know why it was ever done even in trucks and vans. I still want on though. Just to say "hay, yall check this out...."
