I'm going to pick up my aspen today and the owner of the car has no idea what engine is in it because his brother swapped it out 15-20 years ago and passed away. Is there a quick way to tell beside looking for X heads?
How can you id a 340 in the car?

drivers side above the starter, casting numbers, last 4 of them will give the engine cid and revision number, ex: 340-3 or 318-1 etc.
Also on the front of the block below the driver's side head, there will be a stamping of the engine size and build date, etc. sometimes very hard to see.
on the oil pan rail will be a machined pad with a vin on it, might have the full number which might help.
good luck!

Here you go.
Hard to get at if cars on the ground, though you can probably get a peek at it with a mirror.

Remember, heads get moved around. Seeing X heads does not make an engine a 340.

Exactly...

There is an x on the drivers head but an 18 on the passenger head between the 2 rear plugs

Two different heads. Hopefully the 18s were at least upgraded to 2.02s

Small balance so its at least a forged crank.
