If it's for street driving only, I would go with a Holley.
If it's for DD and some mild wheelin. I'd go with either a Holley truck avenger, or a Edlebrock.
If it's for real wheeling, I would go with either propane or a throttle body Fuel injection.
You did say new, but, if you want a really decent carb for wheeling and the road, I would go with a rebuilt, tuned Qaudra-Jet, turned around back wards.
If you are not too stuck with the 4 barrel, a 2100 is another great choice.
