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.
