Therein was the problem with
some remembered stags, single rather than duplex chain drive to the camshaft sprockets?? Did the introductionary course at Rovers, back in the sixties, on the then newly introduced V8.
Enough 'push' with the rods, for power, and pretty reliable too, imo.

: 40,K up on my Big Cats that I loved in that era, meant chains, sprockets, and tensioners, but I absolutely loved the big felines, in spite of their wearing out bits!
