Timing chain

I saw I think a 70's 351W with a plastic cam gear once. Did I win?
Very close! but no, the last of the 289s had them and I got one :(.

I think they were also in the 302's and the 351's as well, till Ford finally gave up on the idea. The funny thing about that one was I had a how to rebuild Ford engines book and it warned that at about 150,000 miles the gear would go. Wish I had read that BEFORE the gear went!
