first question I have to ask is whether you are using an LT1 block or not? I ask because I see that you are trying to use a LT1 "hot cam". I've personally never messed with an LT1 before but if I'm not mistaken I believe the cam between an LT1 and a Gen I small block are not interchangeable. I could be wrong but I'm almost certain.

The shortblock with the -4cc flat tops along with a 72cc head will put you at 10.2:1 so that is right about where you want to be, I didn't look at the specs on the cam you chose but I would assume that you would want to with around a 230°ish @ .050 cam with around .525-.550" lift.

Everything else sounds pretty good, although I've never fooled with an FI set up either, I like good ole' simple carbs.

I've wondered this same thing. I found out it's a '96 block (1024388C). I think it's from GM's crate motor line. I believe it's Gen 1 though, but when I search for parts like on summit racing and I put in '96, only LT stuff comes up. So I leave the '96 out and put in Gen 1.
When I requested a cam from Lunati, I said a '96 block and the LT cam is what they came up with. Once I actually order, I would call them up and discuss what I have.

Thanks for pointing that out though. I would like to hear more on what everyone else thinks about this Gen 1 & LT stuff.

The 96' block could be an LT block because it wasn't until around 97-98 that they started using the LS blocks regularly. But more than likely its a 96' gen I block with a OEM roller cam. You need a OEM style roller cam, not a retro fit style roller cam. Also you will need OEM style roller lifters and not retro fit roller lifters. Typically the OEM style is slightly cheaper.
