Greetings arepoff!!

OK. The idler gear between the crank and the cam explains a lot. You will be OK with the timing chain and sprockets set up. As to engines where the camshaft rotates opposite of the crankshaft, there are many, but to name a couple of examples, International Harvester tractor and industrial engines, and the same with John Deere tractors and industrial engines, and Chevrolet inline 6 cylinder engines. There are more, but too numerous to mention here.
