Who's running a Weber?

I have a Super Six 2 2 barrel intake that I'm getting ready to stick on Hoopty and I'm really thinking the best route for a carb may be a Weber. I like the WK551 Jeep conversion but I'm not sure whether to go with the 32/36 , 36/36 or the 38/38

I'm bone stoke with a 3 or the tree.. will be adding 2.25 exhaust

Opinions for the best route to go with as little as tuning as possible? The ol truck doesn't go far so economy is not a factor.
