Magnum instead of 318?

According to Hot Rod magazine.

Mopar's Magnum 360 crate engines were offered in 300- and 380hp versions, both based on the production Magnum 5.9. The higher-powered engine comes with higher-compression pistons, a long-duration camshaft, and a single-plane Mopar Performance intake. Far more basic, the 300hp version is the same engine as in your typical Durango, van, or Ram truck. With the 300hp crate you get a bone-stock production bottom end, complete with the stock truck pistons and cam. Changes are only the addition of a center-sump passenger-car oil pan, an LA engine-style front cover, a conventional distributor, and a two-plane carbureted intake to replace the factory "beer-barrel" MPI injection system
