Magnum vs la timing chain cover

If I recall...caution because the Magnum water pump turns in the opposite direction than the older LA engines did. Serpentine pulley arrangements may/ will be designed for this, specific to the engine.
By the way...just so you know a 340/360 double roller timing chain and sprockets fit and work within the magnum timing cover. as well the windage tray 340/360 also works but longer main cap bolts are required ( not much longer, I used the 340/360 main cap bolts never an issue).
