What intake for high end 383?

I wouldn't like this to become another pissing match about FI vs carb.
Rather than that, I'd like to hear your opinion in which way would you
go if you were in my situation.

So, without too much details, engine will be 383, Callies crank, Carillo
rods, JE or Mahle pistons, AFR 210's, with ~7500 redline. Behind it
will be full manual converted 700r4 with 2800 stall and 3.73 gears.
I'll probably go with 3200-3500 stall later.

Car will be about 50:50 street/road race car. I really don't care about
any street stuff (comfort, A/C.........). Only thing that I won't from it
on the street is for the engine to run good. Idle will be rough and it
won't be very alive under 2500 or 3000 but I want it to be drivable.

Now, with all that said, I'm considering which way should I go, intake
wise?

Intake manifold will probably be Victor Jr. in either case, but I don't
know if I should go with road race preped carb or FI with 4bbl TB?!

I know that FI has a lot of benefits, but I don't have any experienced
tuner anywhere near and I don't feel like learning and doing it all by
myself. It would take too much time and any mistake (and I'm sure
that there would be some) could be very expensive.
Also, FI is much more expensive. For $1000 I can get a state of the art
carb, and with that money I'm not even near a good FI.

Only FI that I've recently seen and looks interesting is FAST EZ-EFI:

But it's a new system so I'm not really sure how good it would work,
especially with a seriouslly cammed engine.

What do you guys think? What are your experiences or opinions?

if the budget was not a big issue ID have suggested a stack injection unit as its reasonably easy to tune and looks great.
but your really killing your budget a half dozen times over going that route

this style efi intake has several advantages, when your restricted by hood clearance issues, both holley and fast have new efi controllers that self tune, theres no question that efi is better once its correctly tuned

but your easily up to double perhaps triple the cost going with efi vs a decent carb

with your stated $1K budget Id go this route
