727?

Since the 60's Mopar engines have used three automatic tranny bellhousing bolt patterns; one for the big block V-8's, one for the small block V-8's, and one for the slants. A small block V-8 727 will NOT bolt directly to a slant.

Though I have not yet done this (plan to), I am told by most local slant racers that the way to build a strong slant 904 is to remove everything from the case, then fill it with components from an A998 or 999 (the 999 is considered the strongest). Using the 999 parts you'll get 4 and 5 clutch drums and gearsets with 4 pinions.

There may indeed have been 727's in slant trucks, but I have never seen one.
