I looked at that fi Vic Jr. intake they have but the power curve starts at 3500 rpm. I had a standard Vic Jr. on a 350 Chevy with a small stall convertor and 4.10 gears. It was in a 55 Chevy stepside and moved out pretty well. I never felt that it was short on power down low so the 3500 they start the power curve at has me a little skeptical. Especially if it was running mpfi.
Megasquirt makes a controller for 4l60's and 4l80's too called the Megashift. The prices on all this stuff isn't really that bad. I'm sure using the stock stuff and reflashing it would work but think the Megasquirt stuff would be less of a hassle.

Their newest MS3X system is self learning too if you set it up with a wide band 02. You load it with a curve that is close to your engine combo and then it tunes itself from there. Another thing I like about this system is that if you are running a mpfi manifold you can run it sequentially instead of batch mode like a stock system. It seems like you would get much better drive-ability and power.
I'm not trying to talk you out of using the stock computer but didn't know if you knew about the new stuff they had available. It's definitely not the cheapest but the features that are available make the system really tempting.
There are multiple systems available so you kind of tailor it to your needs.
The MS3X also comes with built in bluetooth so you can run the software on a smart phone if you wanted to.
