If I were going to run a carb I would have just stroked a 360 and avoided the hassle of a hemi swap. So, why am I doing the hemi swap? I picked up a low mileage 05 5.7 truck engine and trans for $2000. I think that is pretty low cost for 350+ horsepower and an ovedrive trans and great driveability. Yeah I had to do a lot of fab and wiring work, but that is what I enjoy and there is little cost other than my time. I have a Duster because of the way it looks, but otherwise I prefer modern over 30+ year old technology. I really enjoy my 04 Durango with a hemi. If I had the cash I'd be driving a new Challenger. I want to be able to drive my car whenever and wherever I choose without tuning or adjustment being needed for optimum performance.
I'm surprised no one has mentioned that NASCAR has even moved to EFI.
