Got a box full of carbs... which to use?

I acquired a 2nd truck for parts, mainly the frame which is shot on my truck and it came with boxes upon boxes of parts. one of the boxes is full of carbs and some intakes so now I'm trying to decide which one(s) to rebuilt and slap on my engine. I've got a 22r, aftermarket cam although I'm not sure of the grind as I havn't measured it yet, header and exhaust, 5.29 gears and 31s and 33s for tires. I may also eventually go the 22r/20r hybrid route.

Which carb/intake would be best suited for my setup?

-Holley 390cfm 4 barrel
-Holley 2 barrel, not sure of the cfm. I've searched a number of sites for the list number but no one has it listed, even the old hotrod sites, but I'll assume its a 350 or 500.
40mm Weber sidedraft
45mm Weber sidedraft
Two Weber 45mm downdrafts
and a handful of Aisins

There are also some intakes
Offenhauser dual plane 22r
Cannon 20r for a single sidedraft
A couple unbranded 22r intakes, don't know if their factory. Have different designs for the plate the bolts to the underside of the intake below the carb.

I also have a whole whack of plates and adaptors and spacers so I think I'll be able to mate most of the carbs to the intakes.

Suggestions? Thanks in advance

unless you have the correct linkages etc I would stay away from the weber sidedrafts..no sense in putting to big of carb on a stock 22R or 20R..just dumping fuel
