With the fuel injection you can use the popular 4t60e Tranny and not have to worry about a stupid TV cable to play with, I just like the aftermaket available for a carb hookup, I like all 4.9s being carb or fuel injection, I went with carb because I see potential in boasting this engine to run faster and stronger with some of the aftermarket carb acessories. (reasons why I never epoxied the old unused injector holes)
And living in florida there are no emmision laws 
The difficulty on going carb or fuel injection are the same (If buy buy a plug and play wire harness)
The dist for the carb is very easy also it took me 45mins to make mine. but that's the only hard part to doing carb that I can see.
