Well, some stuff swaps over, bolts, timing covers, brackets, oil pans, etc.
But.........
Do not believe everything you read on the internet or elsewhere.
At times, skepticism is a virtue.

What Mopars4ever said on the receipts/balancing, go check it out skeptically, it may be a good deal (nothing ventured nothing gained). EDIT if parts were swapped I would assume it was balanced).

The forging part numbers might be the same but the finished part numbers wouldn't be. IIRC 318's and other small blocks had a pressed wrist pin, whereas 340 rods all were bronze bushed and the pistons had floating pins with C Clips.

Looks like seller corrected his listing. The power steering pump might be a good grab. https://portland.craigslist.org/mlt/pts/d/sherwood-mopar-318-la-long-block/6938547508.htmlWas...Nearly complete 73’ dated Mopar 318 LA motor with all accessories pictured! Would be a good core motor to rebuild. 1973 is when Mopar started putting the earlier 340 engine internals into their 318 motors. This makes for a great rebuild or stroker!

I bought a 70 318 once for a core with a rod knock for the forged crank, opened it up and it had 4.070 bore TRW forged 340 pistons in it. I still have the block under my shelf as the bores still look great, I just can't convinve myself to put it back together seeing how the normally 165 # block now weighs 122# and the bores sound like glass when I tap on them with my fingernail.
I am not causing global warming, I am just trying to hold off a impending Ice Age!
