Let's be honest....
I agree with Abody Joe. Either go all new under the hood (without the carb) if it is the new Hemi you want. Basically that's what the motor was designed for. I think before long you would have frequent "ghost" issues with trying to get the fuel/motor system happy especially when a computer is involved. I also agree about being happier with a carb/small block set up correctly. Alot easier to work on and less $$$$.
