yes and no. not sure if the area where the plastic cam lobe for the points is the same and i believe the tapper for the flywheel is different and the threads too. but it will fit in the block.

There is the taper issue like delray said (that can be overcome by using a flywheel from the early-mid 1980's), but I dont think they ever crossed with the HS50 engines, some H35/HS40 (late model) do but not the HS50 that I have seen. HS50 have more material on the counterwieghts.
