You've got to wonder how much difference there really is between the BB and SB K frames especially after looking at the pics...I know the Schumacher conversion is basically just lowering the mount on one side..
All I can say for certain is after switching from mid 70's BB spool mounts to the conversion mounts my 440 moved forward and down. Oil pan fits proper now, gained a smidge of hood clearance, fan is more parallel to the rad now, transmission mount fits better where before it was at its rear most adjusted just to get it to thread. When I got the car, the column shift linkage was cobbled and welded but I don't know if that had anything to do with having the wrong motor mounts. Normally I'm not one to sit there and crow about vendor's products, but fitment is night and day.
