Here we go

Lot of those questions are preference, but as far as EFI to carbs...I know there are some who like carbs better but...IMO...it's removing one of the best features of the 5.7L. I did the stock fuel injection on mine because I wanted supreme driveability in all temps and weather, that "get home from work, hop in the car, fire it up, and it will always run well if it's -10 or 110" mentality. I could ramble on for probably hours about why I'd keep the EFI, but it all depends what you want to do with it. EFI is not a cheap way to do it, but IMO is the better fuel delivery system.
