Most USA V-8's use chains to drive the camshaft, even though it is not an overhead one. The sexiest noise out of an engine I have ever heard is when you fit gears to drive the camshaft on said V-8's. Better than a howling S, and that is saying something.......
Biggest difference between a belt and a chain..... belt=rubber, chain = steel
Biggest similarity: S&M people seem to be into both
