If the VIN number has the L then it was a L48 car. And the Previous Owner (PO) put the L82 emblem on the hood. If the VIN has the L, but the block can be determined to be a L82, then it is not the original motor, but could be a L82, and the emblem would then be correct.

You certainly could find a 79 L82 motor ... then have the pad
restamped with your VIN # - but it will never be worth the
investment. True cloning is only worthwhile on very rare models.
L48 vs L82 ? Most times putting a true dual exhaust is enough
to make the L48 overpower the L82. We're only talking about 30HP.
If you want more performance from either, heads-cam-intake-and headers
is the best bang for the buck.

I have a 79 L-82 minus intake/carb/ignition sitting on the floor next to all the other bone yard blocks.
I should have never given away all the top end parts and kept it complete

I'm gonna buy myself an early X-mas present I think and get a pair of Hedman headers, with the true dual undercar chambered from Mid America, no mufflers 
Wonder how much that will boost my HP...hmm
