Some will argue that the carb is cheaper. While some have nice fancy carbs that play the role well, the Hemi was designed via port configuration for efi.

It's more expensive to cost drive ability and efficiency. Power is moot but the other two will suffer in most combinations.

I've got less than $1500 in my efi with computer and wideband. I know it will fire the first time and I don't have to run a side computer for timing. Others will argue but that's my stance.
