slant 6 trans question

The internals depend on which version of the small block 904 you're talking about. Stock slant six 904s had three front clutch plates and discs, two rear clutch plates, and three rear clutch discs. 273s and 318s often used the same internals as the slant six version. Some 318s had a version called the A-998 with more clutches and plates, and there's an even beefier version called the A-999 that came out in 1974 and came behind 360s. You can put A-998 or A-999 internals in a slant six 904 case, though.
