Carb on an LT-1

Has anyone done a carb swapped LT-1? I'd like to see a few pictures, too. I'm looking at a Wrecked Vette with the LT-1 to replace my LG4.
No, I'm not interested in FI- maybe later I'll do the throttle-body... I know GMPP has the manifold...
Thanks!

I should have written - the manifold for carb swaps!

LT1 was built between 1992 and 1997 and GMPP makes an intake manifold to convert them to a carb. You will need to delete the optispark and find an HEI distributor with the correct melonized gear and the lack of a mechanical fuel pump provision will require an electric fuel pump.
