Thoughts on new carb !

Looking to replace my old Holley carb, it is a OEM part from a Ford no service parts available, I see Holley has a Classic 4160 , 0-80458SA and a Holley Street Warrior 4160,0-80457S, along with a Brawler Die cast unit, BR67270

Not sure of the difference of the Holley Classic and the Street Warrior, at this point I like the Brawler for the 600 cfm br67270 it is around 381.95 vs the Classic for 453.95 and the Street Warrior for 440.95.
