I doubt it's that simple. a carb is a carb is a carb. as long as it is the proper size and the linkages can be hooked up, it'll work fine. my suggestion is the do the engine swap first, then worry about changing carbs. too many changes all at once can compound troubles and make it even harder to diagnose any issues. keep in mind that the bolt patterns between carbs are different and an adapter plate may be necessary.
