Outer Limits 4x4 Board

Looking at putting a 350 holley onto my 3F. Has anyone else done this and ho did they set up their carby. Did you have to change the jets to suit the engine or was it just a tuning process? What did you tune?
Do you have to modify the float or anything like that so it doesnt starve for fuel on hill climbs or is it alright?

and what about putting one on gas? will it work then?
