If you have the money,and you are not good with tuning carbs,then yes go EFI.

Me personally,I like to work on my cars for fun,and carb tuning is one of my favorite things to do. It cool to see the diff from changing one little thing. You pretty much only have to mess with a carb(once tuned right initially) if you are changing elevation and/or weather change,and at that it is usually just a jet change.If you get a wideband a/f gauge it makes fine tuning a carb very simple.
