Just look for the best condition vette you can find for the best price out there. Don't get hung up on L82 or L48 you can build up the engine anyway you want. And most guys dump the old SB and put in a new 350/350hp SB for less then redoing the old one. The only things you need to deside is whether you want AC, Auto (don't know why anyone would) or pwd windows. Me I found a 79 L48 4spd w/no options. That's the way I wanted it. And it runs like a bear (after some engine mods). Good luck

In '80:
L82 vs L48:
forged vs. cast crank
4 vs. 2-bolt main block
'350hp' cam vs '300hp' cam
9:1 vs. 8.5:1 compression
Piston pin clearance slightly greater on L82
230hp vs 190hp
I'm assuming the exhaust was identical on both L48 and L82 (2-1-2). All interior accessories/trim levels were avail on either. Although, I believe L48 was the only T-10, 4-speed equipped, Vette avail with a 350 in '80.
