I noticed a metal/polymer gear being developed by one of the Winston Cup mechanics in 2001, who tested it in a race car for a season with minimal wear. But the last time I checked, they werre only making them for Chevys. So its news if they built some for a 351-C which has a unique gear size. Be sure they know the difference between a 351-W and a 351-C. The two Fords don't interchange.
