How about modern era Mopar engines? I've got a pair of single overhead cam Mopar 2.2 inline four cylinder engines that were used in Mexican Formula 2 open-wheel road racing competition held between the mid '80s to the mid '90s.

These engines have all the best high compression internal parts along with a dry sump oiling system, crank trigger ignition and side draft carburetors.

Full-bodied mid size Dodge race cars of the same era were equipped with dual overhead cam cylinder heads made by Maserati!
