Carl Payne: The main differences to the new 5.2l and the old 318 are in the block and heads. The new block has roller lifters, with a new lifter angle, and has bosses for the lifter retainers. The heads are high-swirl / high-flow heads, and the Magnum has a better intake. Some changes were made to commonize the 5.9, 5.2, and 3.9 V6 engines.
Gary Howell: "The Magnum blocks are physically the same as the earlier LA engines, except the oil passage for the shaft mounted rockers is not drilled, because the Magnum engines oil through the push rods. The boss is there if you need to use the old style heads."
