[DeTomaso] Steel dist. gears

[Daniel C Jones]

The MSD gear is a melonite QPQ coated iron alloy.  Melonite QPQ is a
thermochemical (molten salt bath) case hardening process improves wear
resistance and lowers friction.  MSD claims they use a proprietary
formulated ductile iron and their advertising says the gear is designed
specifically for hydraulic roller cams.  Since it doesn't claim
compatibility with solid roller cams, the gear may be compatible with
austempered ductile iron cam cores but not 8620 or 1010 steel cam cores.
I'd call MSD to see what they say.  Crane claims their steel gear is
compatible with induction hardened or carburized  steel cam cores.
Current pricing for the Crane gear is $71.95 at Summit.
