Dear Malcom:

None of the parts are interchangible.

The 6th series Speedster used a hopped up 384ci Custom 8 motor with higher compression, hotter cam, and different carburetor. Although not documented, based on my experience, I also think they had a very expensive crankshaft that was far more stout than otherwise.
