Seems to me in the back of my mind PART of the slant drive fits something else, don't remember if chain or one sprocket, etc........
EDIT found this...........
Slant 6 / Small Block V-8 Parts Interchange - Slant Six Forum
Small block parts that can be adapted to a slant include solid lifters, valve springs (check installed height), rod bolts, main bearing bolts (make sure they don't block oil passages). The crank snout is the same size as a small block or a big block so balancers can be adapted but may require some machining. The lower timing sprocket is the same as a big block as is the timing chain. The cam sprocket looks similar but has a different offset.
