I need some quick questions answered...

You know what opinions are. Just like --------, everybody has one. Here is mine. I've been through the mill trying to make fuel injection work for this swap. Spent more money on reprogramming computer and special wiring than I care to think about or remember. Price of programmable controllers are out of sight. I realize using the RFE45 transmission sounds like a good plan for the overdrive but you need to understand the amount of effort required to make it fit floor pan, crossmember and need to custom build rear transmission mount. Better have a fully equipped shop. Been there and done that. My suggestion is to use MSD 6, the 6013 hemi controller and some transmission other than the RFE45. MSD does not require 02 or knock sensors. Nice, clean and easy hookup. I am using carburetor. Many intake manifolds available. No special high pressure fuel pump required.

However, if you are bound and determined to use fuel injection I have available a 20 gallon aluminum tank with Chrysler fuel Injection pump installed in it.

I totally appreciate and understand why some people choose to go with a carb and the MSD controller. Here's my view just to give another perspective.

Why install a modern engine without taking advantage of all the benefits? If I were going to go the carb route I would have just stroked the 360 I have and used a 727.
Yes, I had to make a custom mount for the trans. All it took was a welder, some metal, and a cutoff tool and air compressor to do the fabrication. I'm excited now to know that makes my 2 car garage a fully equipped shop.
Yes, I had to setup the fuel system. I could have spent some money to buy everything done for me, but I chose to modify the factory truck pump and my tank to make it work to save money.
Yes, I had to go through the wiring harness using the service manual and it took some time and patience and study of all the connectors, but it cost me very little. Mostly for relays, solder and a fuse block.
No, I didn't need a programmer to get it running, but I will likely end up using a diablo to give it a performance tune when I finally get it on the road.
Yes, I had to order my headers with O2 sensor bungs. and I plugged in all the sensors including knock, temp, emissions, etc.
I think the key questions you have to answer are:
What are your goals for the project?
Do you have the skills and patience to do what needs to be done for the intended outcome?

I love the Studebaker plan. I think For A Bodies Only has the best information no matter what route you take.
