5.7 Hemi injected or carbed or 383 carbed?

Looking for 5.7 cost comparisons:
Stock Hemi with stock injection
Stock Hemi with intake and carb
Mild 383 with aluminum heads

I prefer to do the Hemi, but the 383 is ready to drop in. My biggest question is the cost comparison between the Hemi options. I have found some used, takeout Hemi's in the $800 to $1500 range. I'm sure the Hemi's will need extras to make them function, I would think the carb version might be a little cheaper and less complicated, but the 383 basically just needs 12 volts and ground. Would the carb version of the Hemi be just as simple? I'm sure there is someone here that has all this worked out on a spreadsheet somewhere. Ha!

Thanks!
