I am going to need new motor mounts on my 1977. L-82.
Does anyone have recommendations on which brand to go with?
There seems to be so many to choose from in brands and price.
What are some “ decent “ replacements to go with?

Is your 82 stock or have you added HP and TQ?
Do you want rubber, poly, or solid mounts?
How do you drive your C3?
Could make a big difference on what you should use for motor mounts.

It is stock. No added Hp. Would prefer to pretty much stay stock.
I mainly just cruise. Not hot rodding it around.
By all means if you're going with a stock type rubber mount look for the interlocking motor mounts if at all possible.
They're not difficult to find, and are the outcome of Chevrolet's big recall back in 1971 after experiencing a spat of motor mount failures, mostly on the driver's side due to torque. These relieve the major stress on the molded rubber between the engine and the frame part of the mount. The mount can isolate normal vibrations, but after moving just slightly, the two halves lock onto each other to prevent undue stress and separation.
Attached is the story behind the motor mount saga.
I went through a very frustrating time this summer looking for properly fitting motor mounts for my '72. It appears most general retailers are selling the Anchor brand. I went through Rock Auto, Advanced Auto, and an eBay seller (who swore his mounts were old stock USA made). All three sets were no-go because the ears that slide over the frame horns were either waaaay too large - as in a 1/4" slop - or too narrow and wouldn't even consider mating with the horns. All of these were Anchor brand; plus, I had the originals to compare fit and these just wouldn't do.
I ended up going with Corvette Central's reproduction, which they state is a true repro. The fit was a tad snug but 5-10 minutes with a hand file and both sides slid right over the horns and all of the respective bolt holes lined up perfectly when the engine and trany were dropped back in a few weekends ago. They are not inexpensive, compared to the general retail Anchors, but in my opinion worth it to save on the frustration of ill-fitting parts.
I agree with the above from GUSTO14 and 67:72.
Good quality rubber interlocking mounts would be the best for your application.
Buy good quality.
Like many things, you get what you pay for.
Someone here posted a picture of his rubber mount with two through bolts added to keep it from pulling apart the rubber. My ‘78 stock l48 tears thru motor mounts every couple of years; always on the left. Kept rubber on the right, but replaced with poly on the left, and I haven’t been able to break it yet. A little unsure of the heat resistance of the the poly mounts near the exhaust manifolds.
I really liked the 2 bolt addition to rubber; drill thru the holes for rubber on one side and thru the steel plate on the other side and add two bolts from the hardware store.
