Magnum crate help

Picked up a Mopar crate that was advertised as new and it does appear unused. Seller states its a 380hp version. The yellow sticker at the rear of the block is unreadable. Serveral questions come to mind. I noticed that the crate motors come with an LA style timing cover. Does this mean that the only thing i need to do to use a mechanical fuel pump is get the cam snout extension? Does this cover mean it has an LA style water pump? The date stamp appears to show its a '92 block....so is this an late LA motor with magnum heads and what does that mean as far as what model crate motor is, i.e. what HP and when it was assembled. It has the M1 dual plane manifold. There are dot style numbers and letters on the front of the block; 3NK 5.9 2842 1 205AC 268. Outside of the 5.9, any ideas? There is a long bolt protruding out of the lower left bolt hole of the timing cover...? Can I use my pulleys, alternator and alternator brackets from my 340? Im trying to avoid taking a head off to see what pistons are in there.
